ext2 fs not properly updated upon dismount.

Yesterday I posted the observation that consistantly, a root file-system
needs some repair upon startup even though fsck normally checks to see
if it was dismounted properly and doesn't not normally check the whole
drive unless there was an umproper dismount or the mount-count has
expired.

Booting any three of my systems with init=bin/bash and running fsck
manually always finds something wrong that has to be repaired.

Here is an update. It might point to the problem. If I don't set up
a swap drive, the problem doesn't occur. My swap partition is /dev/sdc2,
not shared with anything, while my root file-system is /dev/sdc1.

The swap partition is 132 megabytes.
