Hi,

I created the installation floppy from "kern.flp". Removed it from the
drive, to make it read-only.
I then put it back into the drive and do, as root:

# mount -t ufs /dev/fd0 /mnt
# umount /dev/fd0
umount: unmount of /mnt failed: Input/output error
#

It's still mounted! I have to take the floppy out of the drive, make
it read/write, put it back in the drive and do the umount. Then it's OK.

The following is also fine:

# mount -t ufs -o rdonly /dev/fd0 /mnt
# umount /dev/fd0


Is this normal, or what?
Thanks,
Rob.
