Bug Description

Edgy i386 system (upgraded from Dapper). Login with GDM fails, as /dev/null has permissions of 600. /var/log/daemon.log contains messages such as:

Oct 11 20:11:46 localhost gdm[4558]: Cannot open /dev/null, system on crack!

Running "invoke-rc.d udev restart" fixes the problem until the next reboot.

Thanks,

Interesting. Could you run the following and attach the output:

  ls /etc/rcS.d /etc/rc2.d

Thanks

Also could you attach a copy of /proc/mounts

Where did /etc/rc2.d/S03udev come from?!

Actually, your rc2.d is entirely buggered -- with things that should only exist in rcS.d in there

The double-udev is what caused this, the second udev would temporarily remove /dev/null and overwrite the permissions
