Unfortunately, fat isn't well designed.

That works as long as udisks picks the defaults they want, but then if
they want a non default mount option ( or location ), they have to
specify it in fstab.

That ties it to the specific volume.

Maybe something like:

/dev/fd0 /mnt/floppy auto,vfat utf8
/dev/fd0 /mnt/floppy auto generic-options

The auto would trigger blkid to identify the filesystem, and then only
if it matches one of the additional listed filesystems would that line
be applied.

I suppose that would also require changing other utilities like udisks
to understand it?
