These sound like better solutions; I encountered the problem when trying
to boot with an msdos fs cartridge in when I had an ext2 mount in the
fstab (didn't like that, it didn't). In the configuration you suggest,
one would have two mount points (e.g. /jazext2 and /jazmsdos), two
entries to mount /dev/sdbX on one or the other but noauto, and then a
user could type in e.g. mount /jazext2 or /jazmsdos from userspace?
Does your final remark mean that the same user cannot just
umount /jazext2
(change disks)
mount /jazmsdos
or is it darker and deeper than that?
Thanks for the suggestion,
