fsck done on every boot

[Hans Streibel]

After one of the last dist-upgrades for Ubuntu Precise an fsck is now done on every boot.
Booting succeeds with no fsck errors reported.
However after the system came up tune2fs says that the disk is not clean.

Booting the machine in recovery mode and doing a manual fsck in this mode
does not help either. Directly after that manual fsck tune2fs says that the
disk is clean. However a manual fsck is run again at the next boot.

Nothing is written to logfiles in /var/log/fsck
