Hi.
Funny... one of my filesystem has gone read-only without my command...
As root, I get these:
=================================================================
# rm /usr/bin/bous
rm: remove write-protected regular file `/usr/bin/bous'? y
rm: cannot remove `/usr/bin/bous': Read-only file system
# cat >/usr/bin/gal
/usr/bin/gal: Read-only file system.
# ll -a /usr
total 232
drwxr-xr-x 19 root root 4096 Oct 11 2003 .
drwxr-xr-x 25 root root 4096 Feb 15 15:50 ..
drwxr-xr-x 2 root root 61440 Aug 1 2005 bin
# df -h

/dev/hda2 6.3G 5.8G 160M 98% /usr
# grep hda2\ /etc/mtab

=================================================================
Thanks.
