Does not work here.
# mount /dev/fd0 /floppy/ # mount /dev/hda1 /floppy/test/ # umount /floppy/ umount: /media/floppy: device is busy # touch /floppy/foo umount -f /floppy/ umount2: Device or resource busy umount: /dev/fd0: not mounted umount: /media/floppy: Illegal seek # touch /floppy/foo2 # mount /dev/fd0 on /floppy type vfat (rw,sync) /dev/hda1 on /floppy/test type vfat (rw)
In other words, your suggested method does not work here. (Kernel 2.4.18, util-linux-2.11n)
# mount -o remount,ro /floppy/ /dev/fd0 on /floppy type vfat (ro,sync) /dev/hda1 on /floppy/test type vfat (rw)
This, however, seems to work.
