Subject: [PATCH] systemd: install all dracut units in /etc and let the
 generator cp to /run

All custom units, which should appear in the system later on should be
installed in /etc/systemd. They should have a guard like:
ConditionPathExists=/etc/initrd-release

So, we can later query via systemctl:

$ systemctl status dracut-initqueue.service
dracut-initqueue.service - Dracut initqueue hook
 Loaded: loaded (/run/systemd/system/dracut-initqueue.service; enabled-runtime)
 Active: inactive (dead) since Tue, 10 Jul 2012 16:01:22 +0200; 1min 37s ago
         start condition failed at Tue, 10 Jul 2012 16:01:23 +0200; 1min 36s ago
 Main PID: 173 (code=exited, status=0/SUCCESS)
 CGroup: name=systemd:/system/dracut-initqueue.service
