Bug#870692: The dmraid issues

Even if lvm worked well before with, afaik, the same behaviour of
dmraid, after digging a bit, I tend to blame dmraid probably a bit more
than lvm.

There are some issues with /sbin/dmraid-activate, which tries to  parse
/proc/cmdline and conclude if the device is root, and if so, using the
-Z switch. This fails with "root=/dev/mapper/some-vg-root" and comparing
this to "/dev/sda", of course.

There are also other issues, like when /dev/sda is param, this goes into
$NodeName, and then operating on /dev/$NodeName (which then is
/dev/dev/$NodeName of course) and failing.

Would it be advisable to file another bug for dmraid and link these two


PS: For people needing a quick'n'dirty workaround:
put the -Z in the line of /sbin/dmraid-activate where there's a dmraid
-i -ay without it, and do an update-initramfs -k all -u.
(I don't believe the underlying partitions will be missed a lot. Correct
me if I'm wrong.)
