So I finally plucked up the courage to follow Davy Gravy's Lenny instructions here http://forum.buffalo.nas-central.org/viewtopic.php?f=18&t=5736&p=72241&#p72241
on my new 2nd LS Live.
All went very smoothly with the install and I've done a full aptitude upgrade - so far so good.
I planned to switch from the XFS I've been using with Freelink to JFS as its supposed to be faster but I just can't mount the device.
The kernel seems to have the option
loststation2:/etc# ls /lib/modules/188.8.131.52/kernel/fs/jfs/
and I can happily format and fsck the device
loststation2:/etc# mkfs.jfs /dev/sda7
mkfs.jfs version 1.1.12, 24-Aug-2007
Warning! All data on device /dev/sda7 will be lost!

Filesystem is clean.
But it just won't mount.
loststation2:/etc# mount -o noatime -t jfs /dev/sda7 /mnt/disk1
mount: unknown filesystem type 'jfs'
Any ideas? Am I doing something dumb?
