Trying USB external disk that has ext4 partition /dev/da0s1 and NTFS
partition /dev/da0s2,
   at the moment ext4 doesn't appear to work 'out of the box' - or my mount
command is boo-boo

[root@p00ntang /usr/home/waitman]# uname -a

[root@p00ntang /usr/home/waitman]# mount -t ext2fs -o ro /dev/da0s1
/mnt/linux
mount: /dev/da0s1 : Invalid argument

WARNING: mount of da0s1 denied due to unsupported optional features

[root@p00ntang /usr/home/waitman]# mount
/dev/ada0p2 on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
/dev/da0s2 on /mnt/music (ntfs, local)

checking to see, maybe need kernel support for ext compiled in (which
doesn't sound so much "out of the box")
