[Pkg-sysvinit-devel] Bug#529498: flexible fsck the conservative approach

[Ralph Ulrich]

Here is a patch to flexible fsck in a conservative manner in the sense 
of doing fsck at boot time as ever.

- You will see free mounts until automatic fsck.
- You can force fsck at boot time in which case Mountcount is reseted.

Edit the root entries of resulting /boot/grub/menu.lst to your needs:
