okay so long story short, you only want the mdadm.conf updating in AIF. there's a catch about your proposal though: - it's hard to parse fstab - you would only know the blockdevices after user configured fstab, which is after prefill_config (note the *pre* fill part. this stuff is supposed to happen so that the user can change the config manually after it)
why? Couldn't a mdadm -Es > /mnt/etc/mdadm.conf be suffice? I don't think you would have to parse fstab, All that you doing is makin a mdadm.conf...which you can do after thye raid is constructed. mdadm -Es > /etc/mdadm.conf mdadm -As And the mdadm.con is made and the array is started.
is it not an option to just look at all blockdevices? for example, what do you have in /proc/partitions on your raid system?
