This flaw is notable, unfortunately. However, this is a matter of permissions really. If only group floppy has access to touch the floppy device (or other removables for that matter) I think you will find the problem is at least mitigated. Why the hell would any multiuser machine let non-local users access the removable media in the first place?

Automount does not seem to deal with USB storage devices very well IME.. With a USB removable device you have not only the problem of automounting the thing, but that the thing may be a different device each time you plug it in. I can't imagine that supermount deals with this in any superior manner really, but it is infinitely easier to configure! That is, if you can get it to compile.

A standard ISA-mapped floppy controller's drive can be ejected in the middle of a write. You can't deal with that in any meaningful way. -- Joseph Carter <email@example.com> Now I'll take over the world <marcus> dunham: You know how real numbers are constructed from rational numbers by equivalence classes of convergent sequences? <dunham> marcus: yes.
