Okay, this update is a bit more tricky and the patch I've included is not very nice to be honest. So the patch causes "mdadm --udev-rules" to search for the right store path using /proc/self/exec. This has the disadvantage that we could end up having /run/current-system/bin/mdadm in the rule file. But on the other hand, when we're on NixOS, we don't need to use that command *at*all*, so we should be safe. The patch also sets BINDIR to /sbin, which causes the included rule and systemd files to not work out of the box on NixOS. But we have a substituteInPlace where we do rewrite /sbin/mdadm to the right store path in our udev rule generator, so that shouldn't be an issue. I've tested this using the mdraid installer test and it succeeded. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
