So upstream recently released hal 0.5.12 and it's maintained by crazy who seem to be a bit busy currently, and I don't really wanted to bump his pkg (actually I tried and I failed), but I bumped our udev pkg yesterday so we no longer has libvolume_id. So I backported the relevant patch from git and it seems to work. ;)
(Actually the header is informative, but fake as I created the patch from scratch, based on the one which was in git.)
