56e6ddb8e5 compose: Change /etc/default/useradd to use HOME=/var/home
For a long time I've resisted encoding "policy" into rpm-ostree
as much as possible.  Doing so makes it more distribution specific
for example.  That said, for `/var/home` there argument for doing
this in rpm-ostree is that we already make that symlink in our
hardcoded rootfs.  So we might as well do the other fixups for it.

40be3fb1cf Add recommends to treefile (default on)
This is for: https://github.com/projectatomic/rpm-ostree/issues/718
But I'm not going to close that issue as this only does the server
side, and I think we should support it client side too.

Since I wrote that issue, we ended up skipping the `dnf_transaction_depsolve()`
API, and hence we don't need to block on a libdnf change.  So
this was quite simple.

d7342731ab Add a treefile option to stop creating /etc/machine-id
We actually want systemd's `ConditionFirstBoot` to fire.  The
primary rationale here is that we're adopting Ignition for Fedora CoreOS,
and having `ConditionFirstBoot=` function will help a lot, as the idea
is it only runs once.

However, I discovered that this breaks the `units` directive for example,
as systemd blows away all the unit state in `/etc`.  The correct thing
to do from the start is to use presets.  We could add an implementation of
`units` which works with this on and instead writes a preset file but...eh.
My plan is to at some point introduce an "epoch" and flip various defaults,
this one, `tmp-is-dir`, the passwd file handling, etc.

See: https://github.com/dustymabe/bootengine/pull/11

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.

9f2db12329 core: Fix fcaps (e.g. ping) in unified core mode
This fixes another thing broken with `compose --ex-unified-core`;
for e.g. `/usr/bin/ping` from `iputils`, the classic example of a filecaps
binary.

As I'm writing this commit message I realize it will actually also
take effect for package layering unnecessarily; we'll pointlessly
break the hardlink.  But eh, it doesn't matter right now, we can
optimize that later.

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
`--ex-unified-core` deployment.

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

Implementation note: this is our first use of GResources, which
is a handy way to embed data into our final binary.

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.

802c1fcb90 compose: Fix --ex-unified-core devino cache (suid bits lost)
With unified core 🌐 we are *relying* on the devino cache
for correctness when using `bare-user` repos.  Otherwise lots
of bad things will happen as we won't hit the happy path from
[this libostree PR](https://github.com/ostreedev/ostree/pull/1297)
(I should probably add an assertion there that we aren't trying to commit
 `user.ostreemeta`).

It looks like I had this working in some of the old unified core WIP patches,
but it was lost when rebasing 🏄.

We noticed this when I was trying to deploy jigdo in FAHC and the system
wouldn't boot as various things rely on those suid transitions.

752166ce3b app/compose: include rpmdb pkglist in compose
We don't want to have to download all of `/usr/share/rpm` just to get
the list of packages used to compose the tree. This is fundamental
information that needs to be easier to discover. So let's stick it right
in the commit metadata. There's various use cases for this information,
including easily checking for and displaying updates and a pkglist-aware
version of `ostree log`.

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.
