initramfs-tools hook script messes up /etc/udev/rules.d

[Danilo Piazzalunga]

On Jaunty, the /usr/share/initramfs-tools/hooks/dmsetup script from dmsetup 1.02.27-4ubuntu1 fails to install /etc/udev/rules.d/65-dmsetup.rules correctly in the initramfs: it creates a file named /etc/udev/rules.d. I suspect this is caused by the moving of /etc/udev/rules.d to /lib/udev/rules.d made by udev 136-1.

This also prevents other hooks (like /usr/share/initramfs-tools/hooks/mdadm) from installing their rules causing the latter to fail (for example, I noticed this bug because a system using mdadm's software RAID failed to boot).

The fix is as simple as adding "mkdir -p ${DESTDIR}/etc/udev/rules.d" to /usr/share/initramfs-tools/hooks/dmsetup, like I have done on my system to get it booting smoothly again.

It's the same problem as in bug #314879 (lvm2).
Attached change fixes the problem for me.

[Scott James Remnant (Canonical) (canonical-scott)]

The fix is incorrect.

The udev rule should be installed into /lib/udev/rules.d instead

So it's mdadm package that solves the problem incorrectly?
