FreeBSD support for ext2fs is a specific instance of the more
general problem that features that very few people care about tend
not to get maintained.  FreeBSD already has a filesystem that is
more complete and faster than ext2fs,[1] so the only people using
both UFS and ext2fs are also running Linux.  If you mount an
ext2fs filesystem r/w, consider yourself a beta tester.


[1]	The designers of ext2 basically took FFS and removed the parts
	they didn't care for or were hard to implement.
