If it's trivial to add newest ext* fs, that's nice. For projects
we'd like to build appliances, there will be decent I/O ( maybe the
newest available journaling FS may help..)
I'm a bit busy now, but patches welcome. Basically it involves
changing the command line argument processing a bit, and passing the
'-t {ext2,ext3,ext4}' flag through to mke2fs. And testing that it
still works. See the febootstrap.git helper/ subdirectory,
particularly 'main.c' and 'ext2.c'.
