While that wasn't exactly my goal (I just wanted to see from the NetBSD
side if the FreeBSD side was actually writing sensible things and not
missing anything or mixing anything up or corrupting anything), it could
indeed help me in doing that.
Anyway this does something slightly different (and better, or worse) on
the FreeBSD side, but still ends up with a corrupted filesystem, as seen
from both sides, though maybe not so bad from NetBSD's point of view:
xbd1: 30720MB <Virtual Block Device> at device/vbd/2064 on xenbusb_front0
xbd1: attaching as da1
xbd1: features: flush
xbd1: synchronize cache commands enabled.
GEOM: new disk da1
# newfs -O1 /dev/da1
/dev/da1: 30720.0MB (62914560 sectors) block size 32768, fragment size 4096
using 121 cylinder groups of 254.00MB, 8128 blks, 32512 inodes.
