After playing around some more hours with initram's i've finally found out what my problem was. It is easier than I though :D Basically my changes in my grub config were already correct, however I completely forgot, that, since I wrote my own init script, arg's like "root" and "init" simply weren't used by my script... If you look at my script, I only check the cmdline for "lvm", so setting "init" or "root" haven't any effect at all :D That means, after modifying my init script, using "/usr/lib/systemd/systemd" as init, systemd booted up. It's still not perfect - it looks like it can't mount other lvm partition's and thus only boot's into maintains mode - but it boot's :) Regarding dracut: Even though I got it to work, it also just bootet openrc and not systemd. Don't know why and I didn't digged further after it worked with my own script. Regarding LVM: As mentioned systemd can't mount my lvm partitions from fstab. Those lvm partitions should be mounted by UUID, but it seems like systemd can't find them, even though there are available afterwards (under /dev/vg0/...). If I comment them out in /etc/fstab (they are not important) systemd boots just fine. I've also set "use_lvmetad = 1" in /etc/lvm/lvm.conf as mentioned at the systemd wiki. Any clue why that doesn't work? -- greetings Michael Mair-Keimberger
