Hier ein Beispiel mit --homehost='eisinstall' im Installer:

Nach Änderung des Hostnamens auf 'eisinstall' und Reboot:

Nun sind im installierten System /dev/md2 und /dev/md3 'local to host
eisinstall'. Das ändert aber an der Ausgabe von 'mdadm -Ds' nichts, denn
das Raid wird assembliert, wenn der Hostname noch nicht gesetzt ist.
Also auch noch 'HOMEHOST eisinstall' in die mdadm.conf der initrd
geschrieben, lilo und Reboot.
Aber auch so keine Änderung:
eisinstall # mdadm -Ds
mdadm: cannot open /dev/md/1_0: No such file or directory
mdadm: cannot open /dev/md/eisinstall:2: No such file or directory
mdadm: cannot open /dev/md/eisinstall:3: No such file or directory

Also auch noch die mdadm.conf der initrd nach /tmp entpackt und mit
angegeben:
eisinstall # cat /tmp/mdadm.conf

Ändert also alles nichts...
