Description of problem:
When you boot into a sulogin mode such as when doing a "linux emergency" 
and run mount, the mounts are displayed with the read-write tag even 
though they are mounted read-only

How reproducible:
Always

Steps to Reproduce:
1.LILO: linux emergency
2.mount
3.
	

Actual Results:  mounts show up as rw but are actually ro

Expected Results:  mount should reports mounts as ro

Comment 1 Bernhard Rosenkraenzer 2002-01-17 19:24:10 UTC 
This is  because mount parses /etc/mtab [saved state] rather than /proc/mounts
[current state].
To "fix" this,

rm /etc/mtab
ln -s /proc/mounts /etc/mtab

Please see the mount man page for details on whether or not it's a good idea
(there are both good and bad points about doing this).
