e7a42f70a9 compose: Add rpmostree.rpmmd-repo metadata to commits by default
This is a revisit of a PR for client-side layering: https://github.com/projectatomic/rpm-ostree/pull/1072
Here though we're doing this by default for server-side composes.
There are a few reasons to do this; first, I'm seeing an issue
in some of our Jenkins jobs for Fedora that hit "mirror roulette"
and end up creating commits that "revert" to older versions temporarily.

While I've [certainly pitched](https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/IMPE6KCRBHCEJH5VBE6ZFIRLPAD743JT/) this as a feature, I think
we really want something like `--force-older-timestamp` - basically
error out if the timestamps on one or more input repos were older.
Not doing that in this patch, but it paves the way to do so.

Second, I'd like to use this data in the `ostree.source-title`
metadata key down the line.  Something like:

`└ rpmmd: fedora-26 (20170310), fedora-26-updates (20171101)`

(This could be a lot nicer if we drive versioning in to the rpm-md repo info,
 and e.g. there's some friendly "week number" style versioning for the updates
 repo now that it's batched...for now we have timestamps)

For CentOS/RHELAH this gets interesting and potentially more verbose,
to the point where we may want to render it more explicitly.

But anyways, let's do this now, as it will be useful even without
an explicit rendering, since users can do e.g. `ostree show` on
a base commit hash to dump the data.

I had a concern that some users may not want to emit this metadata;
they can currently do `--add-metadata-string rpmostree.rpmmd-repos ''`
and that will "win".

d6218e0e16 postprocess: Use names (not ids) in synthesized tmpfiles.d files
Related to: https://github.com/projectatomic/rpm-ostree/issues/49

We want to support "name binding" per client system, rather than
having a hardcoded mapping in our tree.  Currently if e.g. a new
daemon is added as a dependency (or as part of e.g. systemd) it's
easy to silently miss it.

This is prep for doing that binding client side consistently, which is what we
do with package layering.

964ab1f8bc bin/compose: Do passwd checking in commit, not install
We won't have done the postprocessing, so `/usr/lib/passwd` won't exist. Trying

63af4bbdda bin/compose: Expose phases as [install, postprocess, commit] cmds
Right now `rpm-ostree compose tree` is very prescriptive about how things work.
Trying to add anything that isn't an RPM is absolutely fighting the system. Our
postprocessing system *enforces* no network access (good for reproducibilty, but
still prescriptive).

There's really a logical split between three phases:

 - install: "build a rootfs that installs packages"
 - postprocess: "run magical ostree postprocessing like kernel"
 - commit: "commit result to ostree"

So there are two high level flows I'd like to enable here. First is to allow
people to do *arbitrary* postprocessing between `install` and `commit`. For
example, run Ansible and change `/etc`. This path basically is like what we have
today with `postprocess-script.sh`, except the builder can do anything they want
with network access enabled.

Going much farther, this helps us support a "build with Dockerfile" style flow.
We can then provide tooling to extract the container image, and combine
`postprocess` and `commit`.

Or completely the other way - if for example someone wants to use `rpm-ostree
compose install`, they could tar up the result as a Docker/OCI image. That's now
easier; an advantage of this flow over e.g. `yum --installroot` is the "change
detection" code we have.

Related issues/PRs:

 - https://github.com/projectatomic/rpm-ostree/pull/96
 - https://github.com/projectatomic/rpm-ostree/issues/471

One disadvantage of this approach right now is that if one *does* go for
the split approach, we lose the "input hash" metadata for example.  And
down the line, I'd like to add even more metadata, like the input rpm repos,
which could also be rendered on the client side.

But, I think we can address that later by e.g. caching the metadata in a file in
the install root and picking it back up or something.

1f31cbb99a status: Render ostree metadata source-title key
Depends: https://github.com/ostreedev/ostree/pull/1296

As I mention in the commit there, I see two uses for this in rpm-ostree; first
in our test suite, and second for OCI-built image imports.

I also took a step further here and inject an `original-origin` metadata
key, though we aren't actually using that yet.  The problem I'm trying
to solve there is that repeated `make vmoverlay` starts chaining things up,
but that gets very confusing.  I think we should always have `vmoverlay` unwind
back to the base ref.  (Or at least do that by default)

a9c8b1fae1 ex-container: Make /etc/shadow 0400 on import, not post-checkout
Switching to the `_CONSUME` flag revealed an "oh god how did I write that"
bug in the previous patch in https://github.com/projectatomic/rpm-ostree/pull/1046
AKA commit: 334f0b89be

The way that actually fixed the bug before was because we were using
hardlink checkouts, and we were operating outside an `rofiles-fuse`
context, we simply directly changed the on-disk object mode.

But with the `_CONSUME` flag we started deleting the files as we write,
meaning that stopped working.

I *initially* wrote a patch to do the same split "prepare/processing/commit"
flow that treecompose and package layering do, but that can't really fix this
bug - we need to do it on import.

So do the chmod on import and drop the postprocessing bits.

e49f7cdd81 app: add --download-only option
To complement the new `--cache-only` option, add a `--download-only`
option. This does exactly what it says: we download the ostree, download
and import packages, but don't actually commit & deploy. This can be
used to effectively prime a follow-up `--cache-only` operation that can
be done during a more convenient/safer maintenance window.

I debated naming the two options `--pull-only` and `--deploy-only` like
the ostree equivalents. Though "pull" felt like the wrong word given
that it's associated more with ostree pulling but rpm-ostree also
downloads & imports RPMs. As for `--deploy-only` vs `--cache-only`, it
seems like `--cache-only` is a more accurate description of the
functionality (i.e. rather than describing an action, it describes a
mode). I also considered `--no-download` to make the synergy with
`--download-only` more obvious. Maybe that's better? Naming is hard...

b811eb61c0 app: support full offline operations with --cache-only
As Colin mentioned in #1035, the new `--cache-only` implemented only the
rpmmd half of the story. Here we complete that story by also ensuring
that when in cache-only mode, we don't download new ostree data nor new
packages. We try to complete the requested operation with what we have.

To do this, we add support for the same `SYNTHETIC` pull that was added
in ostree[1] so that we don't actually pull, but still perform timestamp
checking.

On the pkgcache side, we disable all remote repos and instead insert all
our cached RPMs into the `DnfSack`. Care is taken to still perform
SHA256 verification for local pkg installs/replacements.

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

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`.

(We also override `fedora-release-atomichost` but I'll likely
 submit a patch for that upstream)

e40eaebbe0 core: Use fd-relative access to rpmdb
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)

This fixes `rpm-ostree reload` as root, and supports configuring
it to be enabled for other users as well.  This was overlooked
in the polkit work originally.

b0c75ae900 vmcheck: use --selinux-policy when committing
Let's make SELinux and atomic-host-tests happy with trees we concoct
ourselves by using the new --selinux-policy. (Specifically, we want our
sync'ed binaries to have install_exec_t).

b22d7d764d vmcheck: rename build.sh to install.sh
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.
