What is the correct way to keep the mode of /etc/mtab from changing to
root-only read and write when a volume is unmounted?  I inserted and
ejected a floppy disk on my 3.0 Cube and it changed the mode of
/etc/mtab so that nobody but root can use df(1) (the 'df' command).

On a related note, is the fix for this to make df(1) setuid root?  I'm
hesitant to do that, but if that's the only way to fix this problem...

And lastly, on a clean 3.0 system, what is the output of the following
command?:

ls -lg /bin/df /etc/mtab

Thanks.
