9f777c26ee compose: Add --ex-jigdo-output-set
Following up on `--ex-jigdo-output-rpm`, add support for writing the entire set
to an output directory. This is intended for use cases like FAHC, where we're
generating data outside of the upstream Fedora infrastructure. Further, we want
to support having our own history stored reliably, even if upstream prunes RPMs.

Now, this can be interesting even for upstreams like Fedora, as it naturally
captures just the subset of RPMs; doing full history support for that would
likely be a lot more palatable than for Everything.

79f4b4b861 compose: Add --ex-jigdo-output-rpm
Part of the goal of jigdo ♲📦 is to support organizations switching to *only*
providing RPMs. An intermediate step there is to "lock" the repo and jigdo
together; we don't want to update the ref if building the jigdoRPM fails.

Add an option to perform `rpm-ostree compose tree` and `rpm-ostree ex
commit2jigdo` together; notably we generate a commit, but only update the ref
once the jigdoRPM is built.

054b48d55b core,compose: Fix unified core pkgcache labeling
Basically the `rpmostree_context_relabel()` call we had in the treecompose path
for unified core didn't actually have any effect as the core code did a relabel
and unset the array.

I think this may actually be a regression from: https://github.com/projectatomic/rpm-ostree/pull/1137
though I didn't verify.

Anyways looking at this, the code is a lot simpler if we change the API so that
the "normal" relabeling is folded into `rpmostree_context_assemble()`. Then we
change the public relabel API to be "force relabel" which we use in the unified
core 🌐 treecompose path.

This shrinks the jigdoRPM for FAH from 90MB to 68MB.

d9e870be88 libpriv/core: include pkglist for client commits
The new `rpmdb.pkglist` metadata is a cheap way of retrieving the set of
packages in a commit. I'd like to make use of it as much as possible vs.
checking out the rpmdb and setting up a DnfSack.

Of course, in the case of layered commits, it doesn't matter *as* much,
because a layered commit being present in the repo should mean that a
deployment is currently using it, and we should learn to reuse the rpmdb
checkout of that deployment. Though keeping it consistent across both
server and client commits makes implementing `OstreeDeployment`-agnostic
things like `db diff` more efficient too. I also plan to use this in the
upcoming auto-update code.

6a2962fd8b core: Process systemctl preset in %post
Rather than entirely symlinking `systemctl` → `/bin/true`, in order
to e.g. have NetworkManager be enabled, we need to process presets.

This is one of the things that's breaking FAHC where I did a

(Actually it's a bit tempting to run a mass preset pass at the end,
 but for now let's do this)

879c5afefc compose: Write rpmdb to /usr/lib/sysimage/rpm-ostree-base-db
This is prep for a rework of
https://github.com/projectatomic/rpm-ostree/pull/621

For a no-op `rpm-ostree upgrade` (i.e. no updates available), as long as
layering is enabled, we pay the cost of checking out the base tree, *mostly*
only to get the base rpmdb.

This is prep for fixing that down the line by knowing we always have the "base"
tree's rpmdb checked out. Then in the layering case we only modify
`/usr/share/rpm` (eventually that will point to `/usr/lib/sysimage/rpm`).

Teaching `rpmostree-core.c` about this can follow on later.

ca2a651619 commit2jigdo: Synthesize Requires: for jigdo set
Having the "jigdo set" in repodata makes it so we can parallel download the
jigdo RPM with the set. However for now, I kept the jigdo set in the jigdoRPM,
since that way it'll be covered by the signature.

Also, this changes the way we inject metadata to use a magic comment string,
since trying to pass a gigantic macro to `rpmbuild` via its argv didn't work out
so well (it looks like rpmbuild eats newlines). This approach is more robust.

694b798c73 Introduce experimental "rpm-ostree jigdo"
Tracking issue: https://github.com/projectatomic/rpm-ostree/issues/1081

To briefly recap: Let's experiment with doing ostree-in-RPM, basically the
"compose" process injects additional data (SELinux labels for example) in an
"ostree image" RPM, like `fedora-atomic-host-27.8-1.x86_64.rpm`. That "ostree
image" RPM will contain the OSTree commit+metadata, and tell us what RPMs we
need need to download. For updates, like `yum update` we only download changed
RPMs, plus the new "oirpm". But SELinux labeling, depsolving, etc. are still
done server side, and we still have a reliable OSTree commit checksum.

This is a lot like [Jigdo](http://atterer.org/jigdo/)

Here we fully demonstrate the concept working end-to-end; we use the
"traditional" `compose tree` to commit a bunch of RPMs to an OSTree repo, which
has a checksum, version etc. Then the new `ex commit2jigdo` generates the
"oirpm". This is the "server side" operation. Next simulating the client side,
`jigdo2commit` takes the OIRPM and uses it and downloads the "jigdo set" RPMs,
fully regenerating *bit for bit* the final OSTree commit.

If you want to play with this, I'd take a look at the `test-jigdo.sh`; from
there you can find other useful bits like the example `fedora-atomic-host.spec`
file (though the canonical copy of this will likely land in the
[fedora-atomic](http://pagure.io/fedora-atomic) manifest git repo.

fail the `g_assert (sepolicy_matches)` if we already had packages
done with the final label when we go to reuse the cache.

6bf4206223 compose: Add --ex-unified-core
The "--ex" prefix here means it's an experimental option. A tremendous change
here is that start to support non-uid 0, but there are various things to fix there;
the unpacker for example needs to learn to set imported objects fully based
on the rpmfi information (i.e. default to uid 0, since libarchive gives the
current uid by default).

And even when run as uid 0, there are some bugs, though I'm not sure
of any showstoppers yet.  For example, dracut's `dracut-install` calls
`cp --preserve=xattrs` which fails to copy the `user.ostreemeta` xattrs
from a checkout (it shouldn't be copying that anyways...)

Nevertheless, the infrastructure behind this really helps (is almost a hard
requirement for) the [jigdo effort](https://github.com/projectatomic/rpm-ostree/issues/1081).
Which is really only true due to SELinux - we need to import the packages,
then generate the final tree to get the final policy, then use that policy
to relabel all of the packages.

00fab1ec23 compose CLI: fix --repo consuming two arguments
I was trying to figure out why:

    rpm-ostree compose tree --repo repo/ manifest.json

would result in:

    error: opendir(manifest.json): No such file or directory

It turned out to be because we had `--repo` in *both* the `install`
options and the `commit` options. This makes sense since both these
subcommands need to be given a repo. However, in the `tree` case, we
were adding both arrays, which meant we inherited two `GOptionEntry`s
for `--repo`. This confused glib2 which consumed not one but two CLI
arguments when looking for the argument associated with `--repo`.

Our CI didn't notice this because it uses the `--repo=foo` notation,
which doesn't throw off glib2.

Fix this by factoring out the `--repo` option into a separate array so
that in the `tree` case, it only gets added once. Exercise the fix in CI
by using the two argument notation for `--repo`.

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".

We want to support "name binding" per client system, rather than

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.

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`.

d2bd8500da compose: Add tmp-is-dir option to make /tmp a directory
There are a few reasons to do this. First, systemd changed to refuse mounts on
symlinks, and hence if one *wants* "/tmp-on-tmpfs", one would need to write a
different `sysroot-tmp.mount` unit.

Second, the original rationale for having this symlink was that if you had
multiple ostree stateroots ("osnames"), it's nicer if they had the same `/tmp`
to avoid duplication. But in practice today that's already an issue due to
`/var/tmp`, and further the multiple-stateroot case is pretty unusual. And that
case is *further* broken by SELinux (if one wanted to have e.g. an Ubuntu and
Fedora) stateroots.  So let's fully decouple this and make `/tmp` a plain
old directory by default, so systemd's `tmp.mount` can become useful.

Now, things get interesting for the case where someone wants a physical `/tmp`
that *does* persist across reboots. Right now, if one just did a `systemctl mask
tmp.mount` as we do in Fedora Atomic Host's cloud images, you'd get a semantic
where `/tmp` stays per-deployment, which is weird.  Our recommendation for
that should likely be to set up a bind mount for `/tmp` → `/var/tmp`.

For now, this stays an option to ensure compatibility; if FAH Cloud images
want to stay with "physical /tmp", then we'd have to change the kickstart.

a05e256177 compose: Delete /usr/etc/passwd- (and the other variants)

At the point we added that code we really should have *also* changed treecompose

The reason I'm doing this now is because having them in the base tree causes `ex

24faf942df compose: Add --add-metadata-from-json
I'd like to embed structured metadata about the originating git
repository.  See [this example](https://pagure.io/fedora-atomic-host-continuous/c/142b12020d7efe18b56d039304efea102a210790?branch=master).  However, I think what we really
want here is a *single* value which has subkeys.

One thing in the back of my mind too is...we could use this to
enhance our "change detection".  Right now we checksum the sack,
treefile, and treecompose-post.  But down the line, I'd
like to support more sophisticated postprocessing, where the
script might reference external files or the like.

In that case, we could stop checksumming the post script, and rely on whether or
not the git repo changed. (This would conversely mean we would do a build even
if e.g. the repo's `README.md` changed, but we can address that with a
post-assemble content check).

Anyways though, for now, this gets us the ability to more easily drop more
structured metadata in the commit, whether it's input git repos, tests that
passed, etc.

Note a trap that bit me here: since the metadata we write here is *host* endian,
but `ostree show --raw` byteswaps (it needs to since the core ostree variant
is always big endian), we get inverted numbers if the host is little.

I think we should probably canonicalize our metadata to big endian; this should
be pretty backwards compatible since I doubt anyone has been adding raw numbers
so far.

of a normal ostree compose. That's up next on the list.

b81c0cdfda tests: Add ./tests/compose
Our current compose tests only use a synthetic `empty.rpm`, but
this really limits usefulness.

Let's make a test suite that requires an internet connection and
downloads Fedora RPMs and does "real" tree composes.

See the updated `tests/README.md` for more information.

This is still a WIP.
