Changing line 39 of /sbin/mdrun from:
if [ -z "$AUTOCREATE" ] && grep " devfs" /proc/filesystems
 >/dev/null 2>&1 && ! grep "^devfs" /proc/mounts >/dev/null 2>&1 ; then

to:

/proc/mounts >/dev/null 2>&1 ; then

Fixed the problem.. Most likely not the right fix, but it pretty much
tells whats going on ;-)

ie, /proc/partitions is not devfs-munged with devfs compiled in with
2.6, or something..

This bug has a serious impact on several kernel 2.6 users, and a way how
to colve it was already proposed by the submitter.

I don't have a strong opinion, I have no time or motivation to work on
it and I forgot most things about the internals. If you have a working
fix, use it.

Side comment:

I remember that I used some workarounds to simulate arrays in the POSIX
shell syntax. Since Herbert did not want to use mdrun, I do not see why
not switch to use bash extensions... so if somebody is going to rewrite
mdrun or so, consider this.

Subject: mdadm: mdrun fails with upstream kernels 2.6.2 and 2.6.3-rc1

Package: mdadm
Version: 1.3.0-2
Severity: important

mdrun fails to autostart the arrays when using kernel 2.6.2 and 2.6.3-rc1. it
just exits with no errors, with no arrays started. kernel has devfs compiled in,
but not mounted after the initrd is done running.

I suspect it is because /proc/partitions is different from 2.4+devfs (but not
mounted there either)

fix debbug 231823

This is the same kludge/fix as described in the bug report. It seems to work
fine on both 2.4 and 2.6 kernels with devfs compiled but not mounted.

There is only one important limitation but there is no workaround that i know
of. It relies on uname -r or /proc/version.
So a crafted kernel version might makes this script useless but not dangerous.
The same problem affects debian

Hi,
 a patch to fix this bug, based on the previous information can be
found here:

http://we.give.back.to.debian.even.if.we.have.no-name-yet.com/patches/mdadm.231823.diff

It has been tested and known to work both for 2.6 and 2.4 kernels.
The only difference with the suggested patch is to match for ^2.6 instead
of 2.6.

Thanks
Fabio
