Description lars 2000-02-18 07:56:18 UTC

Good morning. Checking indicates this bug is not yet known.

If you by chance (in our case it appeared to involve an unclean NFS
shutdown or whatever) end up with /etc/mtab, mtab~ and mtab~~, your system
will hang directly after remounting / rw. No error message will be given,
it will just hang and loop.

(This is mount trying to create its lockfile for mtab and failing)

How to reproduce easily:
touch /etc/mtab /etc/mtab~ /etc/mtab~~
sync ; shutdown -f (or flip the reset button;)

Quite an annoying error to track down, since it follows even a cp -a of the
root fs to a new partition (one of the first suspects of a box hanging
after remounting / rw is a ext2 error of some sort...)

initscripts should do something about that (remove mtab*), and mount should
_probably_ complain about it instead of silently looping forever.

This is fixed as of initscripts-4.84 and above.
