Nope. just what's listed in the EXAMPLES section of the manpage.

5.x supports more devices, and supports them better :) There are a
numbers of quirks entries in umass.c for misbehaving devices.

You can, but FAT32 is definitely the most portable.

Just newfs on /dev/da# should be enough. You can fdisk or disklabel if
you want, but if you're not going to boot off it I don't think it buys
you anything.
