Comment 10 for bug 1171945

Just tried to reproduce bug on Debian Wheezy, and couldn't. Wheezy assembles the nested raid without issues. Talked to xnox on #ubuntu-bugs, and he told me to look into mdadm's udev rules. I did, and compared it with the one in Wheezy, and the difference is pasted below. If I change the first line (both in /lib/udev/rules.d and in the initrd) from Wheezy, it works as before (ok with normal raids, not nested raids) - if I replace the whole file with the one from Wheezy or just add the GOTO below, it fails to assemble all raids.

Anyone that can help out here? I'm lost after a lot of digging…

thanks

roy
