I don't know. I may have given wrongly the impression that I am familiar
with this matter. I am not at all. I just noticed a very illogical behaviour
when mounting my readonly floppy; that's all.

With my simple mind, I would say: 'mount' should be able to detect that
you do a read/write-mount, but the medium is readonly; so it should
give an error message and NOT mount.

BUT: if it does mount the medium (floppy), then umount should also do
its job; and not, as it is now, refuse to umount.
