DOS FAT? My favourite embedded OS is using this:
http://www.rtems.com/features.html#filesystems
But it's not "multiuser" in the UNIX sense...

If you're just looking for a simple UNIX FS, the MINIX file system is
quite appropriate. And Linux has a fairly portable GPL implementation.
[Sorry for advertising Linux on the FreeBSD list :]
