Subject: [9fans] p9p vbackup fs type endiannes

I'm trying to use p9p's vbackup(8) on a linux powerpc system.

	# vbackup -m /boot /dev/hda3
	vbackup: ffsopen: bad magic 0x53ef wanted 0xef53

Linux statfs(2) says 0xef53 is a linux ext2 partition type. There
is an ext3 partition at /dev/hda3, so vbackup (its call to fsysopen())
is expecting the right fs type, but seems to be getting the endian
obverse of that value.

(The kernel is debian's stock 2.6.18-5-powerpc. P9p is dated 11/08
from http://swtch.com/plan9port/.)

Anyone else attempting to doubly edify linux in this fashion
and seeing likewise?
