Bug#525655: /usr/share/initramfs-tools/hooks/mdadm: warnings

Sun Apr 26 11:29:10 UTC 2009

Package: mdadm
Version: 2.6.9-1
Severity: normal

Got warnings like this:

W: mdadm: You appear to be missing /dev/md1 from /etc/mdadm/mdadm.conf
W: mdadm: If this is required to boot you must add this line:
W: mdadm: ARRAY /dev/md1 level=raid1 num-devices=2 UUID=e28345e7:cf40379b:3407723407727f:ebf0f0b0

on all md-devices except the md0 boot device, but there doesn't seem
to be anything wrong with my /etc/mdadm/mdadm.conf, AFAICS.  I believe
i found a few bugs in /usr/share/initramfs-tools/hooks/mdadm.  See
attached patch (mdadm-hook.1.patch).

Hunk 4 corrects the real bug.
Hunk 1 corrects another bug.
Hunks 2 and 3 correct a quoting problem (unescaped double quotes
inside double quotes).  Quoting devpairs="$(...)" is not even
necessary, as the expression is already protected.

Attached mdadm-hook.2.patch is an unrelated light cleanup.

Cheers,
