reopen 686895 thanks /etc/init.d/checkfs.sh also checks forcefsck to pass -f to fsck, so it needs to be fixed too. It won't be as simple as checkroot.sh because fsck -A can apply to any number of filesystems of any type and checkfs.sh doesn't track specifics when calling it.
Perhaps the simplest approach, if forcefsck is requested, would be to add a first pass of fsck -A -f -t ext3,... and then let the normal code proceed: this saves a lot of complexity and the worst that should happen is that fsck wastes a bit of time doing a fast and clean second check of the involved filesystems after the forced slow check. Also, I can see that at least reiserfsck too honors -f as --force with the same meaning, so I suppose it should be added alongside ext*. -- Pierre Ynard
