No, that would be a bit dangerous as we blacklist other things as well
(such as SCSI drives except optical ones).

Well, if you find a bug in the filesystem probing code let us know.

Not sure - ideally users shouldn't have to fine tune this. 

For FC4 I hope to have an option in the installer for selecting the
default policy and one option would include "allow full use of all
storage devices" (including non-hotpluggable fixed drives, e.g. your FAT
and NTFS partitions), another one could be "read-only access to
hotpluggable drives" and of course an option to completely lock things
down (e.g. no entries are ever added to the /etc/fstab).

Cheers,
David
