Re: systemd landed

I tested this, but did not go very far.
First of all, I had my /etc/fstab from the distro copied to /etc for
/home and /boot, but systemd doesn't like remounting / on ostree, so
it would jump to emergency mode straight away. To make things extra
fun, -.mount is before systemd-journald.service, so nothing was logged
(syslogd has no .service file, so it's not even started), and
emergency.service would just loop because there is no /sbin/sushell.
In Fedora /sbin/sushell is provided by initscripts, so maybe we still
need a gnome-initscripts module?
Once passed that, I reached a black gdm screen. At first I thought it
was some component crashing, except that journalctl was completely
empty, and systemctl status gdm / loginctl session-status gdm had half
of the gdm greeter session each. Reading the few debug logs I got, it
seemed that all dbus session bus communication was blocked, and thus
the shell crashed trying to talk to gnome-session.

This actually brings a more general problem: where do we report
"integration" problems for ostree, such as missing packages or
dependency issues? Is it right to reuse the ostree product?

Should we ship a preset file, and have a trigger that does "systemctl preset"?
It depends on the ability to do systemctl outside of systemd, though.

Maybe it's time to enable gnome-initial-setup, so that we can actually test it?
If one wants, he can still setup the uid and home directory to share
with the host system. Btw, I believe on the majority of Fedora
installations out there it doesn't work out of the box because /home
is on a separate partition which is not mounted automatically at
