Borked system after last nights rawhide update

Hi, I did a big update last night from rawhide and other than the Noveau problem with GDM which has been updated, I didn't notice any problems. Then my system crashed... When I rebooted inittab was missing and udev was unable to find anything (I had loads of udev failures for finding anything within /dev). As yet, I'm unable to get that machine to reboot and return to a desktop (it will get through to being able to log in, but as it can't find any of the groups or users, it can't be logged in). I can boot from a RIPLinux disc and mount the drive, so everything is still there (which is good). Any ideas on how to fix this problem? I've not seen any other reports on here so far.
