still problems...

[root@pepsi /]# df /mnt

/dev/fd0 1407 1332 75 95% /mnt
[root@pepsi /]# mount /mnt
[root@pepsi /]# mount | grep mnt
/dev/fd0 on /mnt type ufs (ro,ufstype=44bsd)

[root@pepsi /]# ls /mnt
[root@pepsi /]# dmesg | tail -3

Will try it ... sometime. not right now though..

(obtw: i can mount /mnt multiple times.. )

[root@pepsi /]# umount /mnt
[root@pepsi /]# mount /dev/fd0 /mnt -t ufs -o ufstype=44bsd,ro
[root@pepsi /]# mount /dev/fd0 /mnt -t ufs -o ufstype=44bsd,ro
[root@pepsi /]# mount /dev/fd0 /mnt -t ufs -o ufstype=44bsd,ro
/dev/fd0 on /mnt type ufs (ro,ufstype=44bsd)
/dev/fd0 on /mnt type ufs (ro,ufstype=44bsd)
/dev/fd0 on /mnt type ufs (ro,ufstype=44bsd)
