Keep in mind that this only works for _one_ drive. As soon as you have
two, this won't work correctly.

If you have multiple drives, you should label them (with newfs_msdos or
mtools) e.g. 'diskA' and 'diskB'.

With GEOM_LABEL you'll then get /dev/msdosfs/diskA and /dev/msdosfs/diskB,
which you can then put in your /etc/fstab;

/dev/msdosfs/diskA	/mnt/diskA	msdosfs	rw,noauto	0	0
/dev/msdosfs/diskB	/mnt/diskB	msdosfs	rw,noauto	0	0

Of course you need to own /mnt/diskX if you want to mount it as a normal user.
