Prep for [rpmostree compose commit](https://github.com/projectatomic/rpm-ostree/pull/1039).
We still want to write the metadata in that path, so having the data

334f0b89be ex-container: Make /usr/etc/{,g}shadow user-readable
For the `ex container` case, there's no security issues here; one shouldn't be
doing user management in these roots at all.

This is for work on exporting `ex container` roots to OCI as non-root. Without
this fix, libostree just tries to `openat()` the object for export to tar, and
fails.

4a4f9952c2 tree-wide: Use a #define for /usr/share/rpm location
In prep for potentially changing it:
http://lists.rpm.org/pipermail/rpm-maint/2017-October/006681.html

Of course actually doing a transition would be harder than this, as we'd need to
add a compat symlink, and even that wouldn't quite be enough as e.g. the
"preview" code would need to learn how to follow the symlink (or just try both
locations).

In practice I think we'd need to land the code to handle both locations, let
that trickle out for e.g. 3 months, then make the switch in our treecomposes.

But, might as well make this change now; using a `#define` makes it slightly
easier to find places that need changing later.

d0b225c0ab postprocess: Init rootfs earlier
There's a lot going on in the final postprocessing; and some
potentially tricky dependencies.  But we can cleanly move up

236dfd723a compose: Clean up internal final postprocess API
It's really way saner if we create the target root dir in the
compose high level.  That way everything relating to actual file names
(and the concept of the "workdir") rather than the "library".

This is prep for [compose split](https://github.com/projectatomic/rpm-ostree/pull/1039)

postprocessing that just works on `target_rootfs_dfd`.

f3c63b6850 app: Unify some cmdline txn processing
We had duplicated code across the cmdline entrypoints for transaction
processing; things like "print pkg diff only if !opt_reboot".

This doesn't dedup all of them - there are some corner cases around
the preview logic in `upgrade`, and `initramfs` also need special
handling.  I'll likely enhance this further down the line for that.

But one reason I'm doing this now is prep for:
[rpm-ostree cancel](https://github.com/projectatomic/rpm-ostree/pull/1019)

Basically, I want to add a `-B/--background` option we honor consistently, and
that'd be a lot easier if we have a combined "start/monitor txn" with the
post-txn option processing in one place.

d31c9da236 app: Call RegisterClient with well-known name, use retry loop
This closes a race condition for having the daemon idle exit.  After
the daemon has released its bus name, the dbus-daemon will no longer
allow messages through that targeted its unique name.

Since the intention of the `RegisterClient` method is to be the "knock on the
door", fix this by directly sending a message to the well-known name.

Second, we need to handle the case where the daemon exits without
replying; @jlebon added a `sleep(10)` invocation after the daemon
mainloop quit but before we `ReleaseName`, and I verified these two
things combine to fix that case.

d4af84d428 Change ex-container to use BARE_USER_ONLY, update core creation API
Switch `ex container` to `OSTREE_REPO_MODE_BARE_USER_ONLY`; this is a good
match, for the same reasons as flatpak. We don't want suid binaries, we don't
want to chown anything, no SELinux labeling, etc.  There's no reason to write the
metadata to the `BARE_USER` xattrs.

The "unprivileged" context as used for `ex container` was a flag that was passed
down, but I think it's a lot easier if things just infer this state by looking
at whether the target repo is `bare-user-only`. Now we just have an
`rpmostree_context_new_tree()` API that handles both container and compose.

45287828e5 lib/compose: Maintain /etc as /usr/etc more consistently
Lots of confusion in the codebase about this. The basic problem is that in
*most* cases, our code doesn't care; it's conceptually operating on `/usr/etc`,
which we could maintain as `/etc` and just rename it back at the very end.

The exceptions though are the `/etc/passwd` handling and livefs. And of course
libostree needs to handle `/usr/etc` vs `/etc` for config merging.

I considered trying to keep things the other way, but while I think we have some
ugly added here in this patch for things where we need to maintain an external
view (`remove-files` and `remove-from-packages`, and boy am I glad we had tests
for those), this ends up being mostly more consistent elsewhere.

One thing that might help is to maintain a fd for it; but that'd be an even more
invasive change.

This also ends up rolling in some unified core prep from
https://github.com/projectatomic/rpm-ostree/pull/940 in the form of
`rename_if_exists()` - basically for some minimal rootfs we may not have
`/boot`, or for that matter potentially even `etc`.

c92ff926f6 app/status: cleaner diff output for replaced pkgs

we can print a cleaner diff in the status to make it easier to grok.

4ad3ea58c6 app: smarter deployment change detection
Commands like `upgrade` and `deploy` need to know if a new deployment
was actually laid down so that it may print a pkg diff if so. This is
implemented by listening for changes to the DefaultDeployment D-Bus
property. D-Bus emits a signal when the deployment variant changes
value.

However, in #595, with the introduction of `pending-*` related keys, the
deployment variant no longer represents data solely tied to that
specific deployment. In this case, because `deploy` operations currently
set the ref to the resolved checksum, it can happen that deploying the
same base commit when the current refspec *isn't* pointing to that base
commit will result in the `pending-*` keys dropping out and a default
deployment change notification going out.

In this patch, we strengthen how we determine whether a new deployment
was laid down by actually looking at the deployment id, rather than just
assuming that a change to the property implies a new deployment.

c08ca8f922 daemon/upgrader: make use of override-commit-ids
Currently, when setting the `override-commit` key in the origin, the
upgrader pulls that commit checksum directly and then updates the
refspec to point to it. This behaviour was inherited from its ostree
version; at the time it was implemented, the pull code didn't support
passing a specific commit for a given refspec. However, we now have
the override-commit-ids option, which will make libostree update the ref
for us.

We change the code here to make use of it and simplify the function.
This also fixes the corner case of local branches: we shouldn't change
the ref if we're on a local branch. This is actually what drove me to
this patch as I was debugging #981.

(Aside: I'm still not convinced updating the refspec is always the
correct thing to do even in the remote case, though it's a bit messy to
disentangle).

f113fc5e27 Rework treecompose kernel processing
Prep for changing `boot_location: new` to use `/usr/lib/ostree-boot`
and `/usr/lib/modules`.  Rework our kernel postprocessing
so that we unify the `boot_location` handling with initramfs generation.

Instead of doing the initramfs first in postprocessing, we do it nearly last,
after e.g. `etc` is renamed to `usr/etc`. This has some consequences, such as
the fact that `run_bwrap_mutably()` is now called in both situations. In
general, our handling of `etc` is inconsistent, although understandably so.

As part of this, I finally got around to implementing the bit from
https://github.com/systemd/systemd/pull/4174 however suboptimal it is; need the
unified core so we can cleanly ignore the posttrans like we do others.  We
intentionally keep the file around in the generated tree so that installing a
kernel RPM per client doesn't try to do any of this either.

This all gets folded together so that the logic for handling the bootloader gets
simpler - in the Fedora case, we now know to find kernels in `/usr/lib/modules`
and can ignore `/boot`.

3ff48589b3 compose: Make boot_location: legacy be an alias for both
We have 3 locations to find kernels now; I can't think of
a reason to support placing kernels *only* in `/boot`.  The
original commit
15ecaacd36
doesn't give a reason, and I certainly can't think of one now.

This makes `legacy` be an alias for `both`, which should be fully compatible.

`/usr/lib/ostree-boot` *and* `/usr/lib/modules`.

150de0087e scripts: Support overriding lua, use for glibc-all-langpacks
Today in Fedora the `glibc-all-langpacks.posttrans` is implemented
in lua, for no good reason.  See:
https://bugzilla.redhat.com/show_bug.cgi?id=1367585

Since that's stalled out, let's add support for overrides.  This
is obviously a much bigger step with more long term maintenance
implications over our current "ignore scripts" list.  But we can't
block either.

This is needed for unified core work:

79086f8c3d core: Use a single tmpdir/ostreetxn for relabeling
I'd like to cut down on the number of tempdirs we make; when
debugging with gdb I often use e.g. `r` to restart forcibly, and
that leaves the dirs around.

Previously we'd make a tmpdir per relabeled package; this hoists it into a
well-known "relabel/" subdir of the per-core tmpdir we make. (A next step here
is to dedup the core tmpdir with the tmpdir that the upgrader makes)

Further while I'm here, let's use a single OSTree transaction for all of the
relabeling; the rationale here is that it's better to do fewer `syncfs()`
operations.

20abc85243 unpacker: Translate /boot → /usr/lib/ostree-boot
At one point `rpm-ostree install libvirt` dragged in libguestfs which in turn
brought in `syslinux-extlinux-nonlinux` which has files in `/boot/extlinux`,
which we rejected.  (That dependency chain appears to have been fixed currently)

For the general case, this is just a partial fix in that we haven't nailed down
the semantics of how updates for `/boot` work.  But in this particular case,
we'll just break libguestfs' `extlinux` verb, which I'm OK with.

Another case is `fwupdate-efi` - we require manual intervention to copy the
data into `/boot` after installing the package.

This is also preparation for [unified core](https://github.com/projectatomic/rpm-ostree/issues/729)
in that we now ensure imported kernels don't end up in `/boot` unless
explicitly configured.

It seems best practice to me to run `%post`s strictly before
`%posttrans`; we're not likely to do parallelization anytime
soon anyways.

In Fedora, today the FAH releases are async of the rpm-md repos, and

dc24dd3105 rollback: allow users to undo a rollback
The new API to find pending and rollback deployments do so relative to
the booted deployment. This caused an interesting behaviour: the first
time a user uses "rpm-ostree rollback", it would (as expected) move the
previous deployment first. but the second call to "rpm-ostree rollback"
would fail since there were now no more rollback deployments.

We fine tune the logic here to allow this, as well as the more general
case of putting the booted deployment back on top.

This fixes a subtle regression from b7cf58e

0d4d6be94f Implement file triggers (%transfiletriggerin) for layered pkgs
File triggers are a post-RHEL7 thing; more information at
http://rpm.org/user_doc/file_triggers.html

There are two notable users I've been testing this with;
`glib2` and `vagrant`.  The `vagrant` one is more immediately urgent,
since it makes `vagrant-libvirt` work, which I currently rely on
for my workstation dev.

I've tested things successfully with `vagrant`, and I did verify that we run the
`glib2` ones when doing `rpm-ostree ex container`.

Long term, more transaction file triggers are likely to live in
"base" packages like `glib2`.  We don't implement those yet, but
extending this to do that shouldn't be too hard.

There was *significant* what I'd call reverse engineering of the
implementation in librpm.  The file triggers code there is spread out
and abstracted in a few different places in the code.  I found
trying to understand what header values were involved to be quite
tricky.

There are some corner cases like multiple patterns that I *think*
this does correctly, but could use more validation.  The main
question I had was - is it required that the patterns for e.g.
`%transfiletriggerin` and `%transfiletriggerun` be identical?

34b5a004a8 daemon: Add a sanitycheck(/bin/true) before we deploy a tree
This is a followup to https://github.com/projectatomic/rpm-ostree/pull/888
but more comprehensive; in the layering case, the sanitycheck runs
after all the `%posttrans` scripts, so we'll get a consistent error message
for the `rm -rf /` test.

We also do the sanitycheck for the "pure ostree" case, as well as cases
where we didn't actually layer packages (including `ex override remove` as
well as simply regenerating an initrd).

There's obviously a lot more we could do in a sanitycheck; as I say in the
comment it's tempting to consider trying to boot systemd (in a fully volatile
config), but for now let's do this. In the end of course the admin has rollback
too.

fee6d06bf4 lib: Expose new API around basearch
For https://pagure.io/atomic-wg/issue/299 we need to make it
more convenient to substitute the architecture in an installation
context.  I plan to use this API inside `rpmostreepayload` in Anaconda,
so we can substitute the same value of `${basearch}` we use in treefiles
since https://github.com/projectatomic/rpm-ostree/pull/305

Now, you might wonder - why do we need an API wrapping libdnf? It's because
libdnf is not API stable yet. We're just exposing a tiny subset. In theory we
could use the Python dnf bindings in Anaconda, but things get slightly weird if
rpmostreepayload depends on dnf. Perhaps we'll do that down the road, but for
now this a small API surface to maintain (forever).

This change reworks the internal `varsubst` bits to take a pure `DnfContext`,
since we don't want to spin up a whole `RpmOstreeContext` just to do some
string substitutions.

b46fc35901 Add releasever opt, avoid opening up host's rpmdb in treecompose
Closes: https://github.com/projectatomic/rpm-ostree/issues/546

Previously, we'd open up the host's rpmdb for both `compose tree`
and `ex container`.  In the first case, because we require root, we'd
succeed.  For `ex container`, we'd spew an error.

Fixing this was trickier than I thought.  First because there was
*also* a libdnf bug here: https://github.com/rpm-software-management/libdnf/pull/307

Second, there's a compatibility hazard here for anyone using `.repo` files that
reference `$releasever`. This actually happened to me with `ex container` as I'd
just done a `ln -s /etc/yum.repos.d/fedora.repo rpmmd.repos.d`.  I fixed
that first by doing a `sed -i -e 's,$releasever,26,' rpmmd.repos.d/*.repo`.

As far as I can see today, none of Fedora Atomic or CentOS AH rely on this. But
in order to enhance compatibility, let's add a "releasever" option. This makes
it easier again to reuse stock `.repo` files if we wanted to do so.

(Also, I realized we can just use `/usr/share/empty` as *the* canonical immutable
 empty directory)

0b1c5eda17 override remove: allow inactive removals
The property of removal overrides dropping out if the package was
removed from the base layer felt a bit too magical and hacky. We really
should remember that wish and re-apply it if the pkg comes back. This is
similar to package layering: requests can become inactive (seems like a
better word than "dormant") if the package is already part of the base
layer, but they don't really go away.

This patch reworks the logic so that removal overrides work the same
way. In the status output, we now have both "RemovedBasePackages" and
"InactiveBaseRemovals" (which is only printed in verbose mode),
similarly to how we have "LayeredPackages" and "InactiveRequests". And
similarly, we also print out in the upgrader during a transaction all
the inactive base removals.

Another cool thing is that we now allow any pattern to be specified at
the CLI. E.g. `ex override remove /usr/bin/strace` will resolve to
strace.

61560e0686 status: rename RequestedPackages to InactiveRequests
In the JSON output, the "requested-packages" holds *all* the requests
for package layering, whereas the "packages" key holds only those
requests which actually caused a package to be layered.

When outputting RequestedPackages, we try to be nice and print only the
"dormant" packages, i.e. those requests which did not require any
packages to be layered since the base layer already fulfilled them. This
is the subset of "requested-packages" not also in "packages". But then,
we could call this subset something much more appropriate than
"RequestedPackages" when outputting.

This patch renames it to "InactiveRequests" to reflect the "dormant"
aspect of them. We also make it only be output in verbose mode, since
it's not as interesting as what was *actually* layered when trying to
understand what the host is currently running. But we do adapt the
upgrader so that it prints out inactive requests during transactions.

943138b132 postprocess: stronger handling for sepolicy in /var
We shouldn't just check that the "targeted" dir exists, but rather that
the actual directory where the modules are stored exists. This fixes a
regression on RHEL in which the new selinux-policy-targeted lists some
%ghost files under /var/lib/selinux and as a result think that the
policy is in /var.

4ee57a6dbd rpmostree-dbus-helpers: generalize pkg sorting
Minor prep for replace overrides.

Let rpmostree_sort_pkgs_strv work on an existing fd list rather than
creating its own, since it may be called multiple times on different
pkgs arrays.

Factor out the logic that calls to sort and inserts the values in the
final modifiers variant dict to prepare for being able to do this

5da409fcad upgrader: Add user-inaccessible private dir for rootfs checkouts
This is part of the saga of permissions and checkouts that
came about thinking about flatpak, but suid and world-writable dirs
are also an issue for us.

There's no reason to make suid binaries accessible temporarily
to users while we're computing a new root.  Similarly, we don't
want anyone to actually *write* to our temporary `/tmp`.  The
simple fix is to make an intermediate dir that's `0700`.

cde3295e26 app: add experimental support for pkg removals
This is one more step towards making rpm-ostree more powerful in its
quest to be the ultimate *hybrid* image/package system. Package layering
allows us to add packages on top of the base package set received from
the content provider. However, we're not able to remove or replace
packages in the base set itself.

This patch introduces a new `override` command, which is for now nested
under the experimental `ex` command. The `override` command will allow
users to modify the base package set itself. The first implemented
subcommands are `remove` and `reset`.

A stub has been provided for the more useful `replace` subcommand,
though much of the needed logic for that operation are implemented in
this patch as part of the `remove` subcommand.

e5294829b8 Add human-readable Title to transaction, render in status
There's a lot that could be done to improve this; we're not setting a title for
`rollback` etc. But I think in practice right now the "deploy" path (which
includes upgrade/install) etc. is most important.

Re-synthesizing a human readable string here is definitely a bit fragile and
going to be a maintenance pain. One thing I debated is having the client send
its commandline as a string. But that would only work for `/usr/bin/rpm-ostree`,
not e.g. Cockpit.

Anyways for now, this is useful and we can always improve it later.

af982ff156 livefs: fix nested continue bug in optimization
There's a subtle but classic issue in this code: calling `continue`

base overrides as well.

b800fae0cc upgrader: refactor to improve legibility
At this point, there are many helper functions that really should just
be made upgrader-aware to make it easier to follow. For example, now
both find_missing_pkgs_in_rpmdb() and generate_treespec() are passed the
Upgrader object directly, allowing us to avoid having to thread through
multiple arguments everywhere. Another example is that the Upgrader now
carries the list of final packages that need to be overlaid rather than
passing it around.

We also rename the functions to better reflect what they actually do.
