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.

68acb1d2be compose-tests: add more tests
Add a few more tests to exercise some of the treefile options. We do
need to also expand test-basic.sh itself to sanity-check the structure
of a normal ostree compose. That's up next on the list.

0c4aaf25de docs: add section about package layering
Add some notes in the manual about package layering. Would be nice to
have `ostree admin unlock` also be part of the ostree manual for a
better contrast of the two.

Looking at the other snippets in the document, this makes me think we
probably should also add wrappers in `/usr/bin/atomic` for the new
commands. Or maybe we should wait until they're not in preview mode
anymore.

603180bcf2 docs: Point compose server intro to CentOS

94a2804b0a compose: support adding external files
This will allow to copy arbitrary files into the rootfs, specifying something like:

"add-files": [["service.template", "/exports/service.template"],
              ["config.json.template", "/exports/config.json.template"]]

It is quite useful when building a container image.
