3f367dbce2 scripts+bwrap: Make script execution cancellable
Prep for implementing `rpm-ostree cancel`, but this works with the way we handle
`Ctrl-C` interactively on a client as well. Being able to cancel a script
execution is quite nice; some of them are expensive, and having one loop forever
has been known to happen.

a9c38d33b8 vmcheck: add SELinux labeling tests
There's a lot of paths in the core related to SELinux policy changes and
relabeling packages. We currently have no test coverage for them. We add
support in the test libraries here to build such packages.

We also add a test that checks both that we correctly relabel RPMs when
the policy changes and that we handle layered packages that install
SELinux packages properly.

1acd834104 Add test infra for ex container, and one test for bash
We have some unit-style tests that run `ex container`, but
they aren't "real"; they don't use scripts for example.  Let's
add tests for this similar to `tests/compose`.

We use a 26 base, but the target repos need to be 27
to pick up the fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1478172

Add some bits to share infra between `tests/compose` and `tests/ex-container`;
basically handling the rpmmd repos. I tweaked things to be more streamlined
there between the `.papr.yml` and the test script.

Right now this is just one test for `bash`, but lays some of the infrastructure
for doing more. One thing that we need to do to improve more here is to better
cache RPMs, a bit like the compose tests do.

c92ff926f6 app/status: cleaner diff output for replaced pkgs
I suspect a common pattern with local replacement overrides is to
simultaneously replace a group of packages that depend on each other in
one shot, as is the case with docker, docker-common, and
docker-rhel-push-plugin currently in Fedora Atomic Host. In such cases,
we can print a cleaner diff in the status to make it easier to grok.

Before:

     ReplacedBasePackages: strace 4.18-1.fc26 -> 4.19-1.fc26, docker-common 2:1.13.1-22.gitb5e3294.fc26 -> 2:1.13.1-21.git27e468e.fc26, docker 2:1.13.1-22.gitb5e3294.fc26 -> 2:1.13.1-21.git27e468e.fc26, docker-rhel-push-plugin 2:1.13.1-22.gitb5e3294.fc26 -> 2:1.13.1-21.git27e468e.fc26

After:

     ReplacedBasePackages: docker-common docker docker-rhel-push-plugin 2:1.13.1-22.gitb5e3294.fc26 -> 2:1.13.1-21.git27e468e.fc26, strace 4.18-1.fc26 -> 4.19-1.fc26

58f8f892fb lib/postprocess: Use O_TMPFILE, not O_APPEND for tmpfiles.d writing
The comment here was wrong; we don't rely on `O_APPEND` here for package

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`.

150de0087e scripts: Support overriding lua, use for glibc-all-langpacks

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

b6705f3feb daemon: Check for updated rpms when upgrading
This closes a longstanding bug - since package layering first
landed, we only checked for newer RPMs if the base tree changed.
In some scenarios like RHELAH, this doesn't matter much by default
since they move at the same cadence.  Except if you use EPEL for example.
In Fedora, today the FAH releases are async of the rpm-md repos, and
there's also COPR which can update more than once a day even.

We should check for both update sources. Luckily we'd already introduced logic
for this in the treecompose case (checksumming the depsolved package sack). We
just need to start using it for client side assembly too.

dc24dd3105 rollback: allow users to undo a rollback
The new API to find pending and rollback deployments do so relative to

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.

case of putting the booted deployment back on top.

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?

d4effe8f47 dbus: don't register if not active

introduce the concept of "read-only" clients in the daemon to only allow
access to non-mutating methods, though let's delay that discussion at
least until the daemon learns to auto-exit.

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.
