Where did you pick up that word? I don't think it appears anywhere in
my posting. The original sentence was: ``I get "raidautorun:
RAID_AUTORUN failed: 19" when nash runs "raidautorun /dev/md0" at boot''

'raidautorun' is nash's internal command used only in initrd boot scripts
and is unrelated to 'mdadm' or the old 'raidstart' commands (has there
even been a 'raidrun' command? not that I know).

'mdadm' and 'raidstart' run from the real root filesystem after it is
mounted.
'raidautorun' runs from initrd precisely to get the root filesystem
mounted. It's built in nash, the 'boot shell' that is part of the
initrd image.

I used 'mdadm' (from a boot CD) to create my RAID MDs, of course. But
when you build an initrd image (even with the stock mkinitrd TSL 2.2
RPM) the 'raidautorun' command will be used inside, you don't control
this.

Seems to me you're mixing the initrd and 'post root mount' environments.

Greets,
