Bug#381007: mdadm: Fails to upgrade with devfsd-style udev

[Bas Wijnen]

Package: mdadm
Version: 2.5.2-7
Severity: grave
Justification: renders package unusable

Ok, not quite unusable, but unupgradable.  Which I suppose may have
security concequences as well.

Anyway, the problem is that during preconfigure, the script hangs while
continuously saying "E: unrecognised device string: /dev/md/0"
Looking at the script, the problem is that this matches
/dev/md*|md*),
but not
/dev/md[0-9]*|/dev/md_d[0-9]*)

This, plus the while true, which perhaps should be
while [ $ERROR -eq 0 ], leads to the endless loop.

I do not have enough knowledge of the purpose of the script to write a
patch just now, but I suppose it's not too hard to fix.

Thanks,
Bas Wijnen
