Description hno 1999-12-23 11:13:45 UTC 
Using initscripts-4.16-1

Due to some yet unknown reason I got stale /etc/mtab and /etc/mtab~ files,
causing the following quite servere error:

a) The system hung at shutdown while unmounting filesystems
b) Likevise, the system hung shortly after remounting the root filesystem
read-write during system startup.

Recovery procedure:

Start the RedHat rescue system image, fsck and mount the systems root
filesystem read-write and remove etc/mtab~

Recommended system fix:

Have the rc.sysinit script flush any existing locks on mtab.
echo >/etc/mtab  (this is already properly done)
rm -f /etc/mtab~
rm -f /etc/mtab~~ (not sure if this is required)

It appears that the cleanup of mtab~ already exists, but way to late in the
rc.sysinit.

Will be fixed in initscripts-4.84, in the next Raw Hide release.
