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`.

I was reading some of the core code recently, and in general I think we need
more comments. I made a pass from the top of the file and got halfway down.

Rather than just letting the scriptlets inherit the daemon's
stdout/stderr, redirect their outputs so that we can set a customized
identifier to make it easier to distinguish from the daemon output.
Also print out the `journalctl` command needed so that users can
investigate the output themselves.

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

The comment here was wrong; we don't rely on `O_APPEND` here for package
layering since we convert on import. I noticed this while I was doing
a grep for `O_APPEND` in the codebase as part of unified core work.
Fix this by converting to `O_TMPFILE`+`GLNX_LINK_TMPFILE_NOREPLACE`.
Prep for unified core.
Closes: #1009
Approved by: jlebon
Prep for unified core work. This was failing due to a bug in libglnx
<https://github.com/GNOME/libglnx/pull/80> but I think this change is also
correct. There's no good reason for us to copy xattrs like the SELinux label
here - rather we want the labels to be reset during commit.
I did a tree-wide grep for other users and the only other case that is odd is
the treecompose `add-files`; I'd say we should change this but out of (a likely
excess of) conservatism I just left a "FIXME" for now.
Closes: #1008

Noticed this pass by while doing a `fedpkg local`. It doesn't actually
matter much since there are no exits possible between the point it's
declared and when it's actually assigned, which I will assume is why our
clang suite didn't pick it up, maybe? Not gonna look into that right
now.

We were directly bind mounting the checked out `/usr/etc` onto `/etc`
which was exposing us to corruption from scriptlets. Since we already
have an rofiles-fuse mount for `/usr`, let's just re-use its `etc/`
subdir and bind mount that instead.
Closes: #1003

We don't need those in the tree, so let's nuke them. This also fixes
subtle compatibility issues between hardlinks and lock files (see #999).

Now that we support overrides, we need the sorter to make sure it goes

Even if we're already initialized, we still need to create the subdir
requested. This would cause relabeling to fail because we try to create
the "relabel" subdir, which never actually gets created.

Amazingly we had 3 variations of this bug in the different
layers above using the `RpmOstreeContext` API (in compose, container,
and layering).
We fixed the first two already, this fixes the last one. We
get a warning if librpm holds a ref to a deleted rpmdb.
Closes: https://github.com/projectatomic/rpm-ostree/issues/987Closes: #994

This ensures we close the rpm database before we start moving
things around during postprocessing, and avoids a warning about
the rpmdb going missing being printed at the end of a compose.

The CentOS tester is currently failing because clang is being passed an
argument it doesn't know about:
clang: error: unknown argument: '-fstack-protector-strong'
We get our version of clang from EPEL, which currently has 3.4.2. The
Fedora clang does have support for the flag (4.0.1).
Anyway, the point of this check is just to find unused/uninitialized
vars and other gotchas. In that sense, we're more interested in what the
latest version of clang has to say.

This PR uses https://github.com/ostreedev/ostree/pull/1156
to ensure that when installing packages containing files with
exact same content, the files will be merged.
When installing packages containing conflicting files,
the error will still be detected at the ostree side.
The checkout overwrite option at rpm-ostree side is also
modified to accomodate the changes made in ostree side.
A test is added for regression
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.
Closes: #981Closes: #984

Also something I noticed while working on #981. When sitting on a livefs
commit, once a user does `rpm-ostree cleanup --pending --rollback`, it's
impossible to redeploy the same booted commit. Let's allow users to do
this.
Closes: #984
Approved by: cgwalters
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).

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`.
Closes: #959
Approved by: jlebon
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.
Prep for further refactoring towards changing `new` to mean both
`/usr/lib/ostree-boot` *and* `/usr/lib/modules`.
Closes: #959
Approved by: jlebon
Make `upgrade` use the same trick as `deploy` to determine if a new
deployment was laid down. Apart from those two, all other operations
that can lay down a new deployment always do so in the happy path.

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:

submit a patch for that upstream)

I was linking to this code from elsewhere and noticed that
for our hardlink breaks we were not using fd-relative even
though we can. Down the line if we fork librpm into a separate
process and do e.g. `--dbpath=.` it'll do it too.
(Side note, I verified that commenting out the hardlink breaking
here was caught by the `ostree fsck` I added to the test suite)

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.

I had meant for this to be in the other PR#968. I originally did both
`make` and `make install` there, but now it only does `make install`, so
let's just rename it to make that more obvious.
Closes: #953
Approved by: cgwalters
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.

Let's make using a custom install tree easier and document the process.
