How? Amiga filesystems don't have a SUID bit, so you can't have a suid
program on one. They don't have device nodes, so you can't introduce
holes that way. As long as adosfs is changed to implement the proper
restrictions on where a filesystem can be mounted by a user, like mdosfs
does, there are no security problems I can see.
