So what should I have in FSTAB and CMDLINE.TXT to use subvolumes but also load from /dev/sda1

ok, it's plain. cmdline.txt is used only to determine which filesystem to start rootfs from - and this you have correct.

to make it work, you have to create root and home subvolumes, create @ snapshots from them and move root / home content to root/@ and home/@ respectively.

exactly this code is used in initramfs/conversion function (ext4->btrfs). I will copy & paste the code for you - and adapt.

Code:

mv /root /root.home
btrfs sub create /root
btrfs sub snap / /root/@
mv /root/@/root.home /root/@/root
btrfs sub create /home
btrfs sub create /home/@
mv /root/@/home/* /home/@

edit cmdline.txt and add to rootfsopts=subvol=root/@,PREVIOUS_OPTIONS...

you don't have to update fstab anymore. after reboot XBMC won't start because home/xbian won't be mounted, but as soon as you install updates, this will be corrected. just log in to RPI and stop xbmc (otherwise it will be respawning over and over again) and remove files from root of the btrfs (which we couldn't move, we just created snapshot and now rebooted from it)

Code:

mount -o subvol=/ /dev/XXXX /mnt
for f in $(ls /mnt); do [ $f != root -a $f != home ] && rm -fr $f; done
umount /mnt

install updates

as I posted in one other thread, beta2 is making any "USB copies" which do not retain subvol structure not working properly. the error you encountered is not the main problem there.

...... and then just hangs - Have to cntl C to end.

and just "ipconfig eth0" or "ipconfig -n xbian eth0" ?

what is the dhcp server ? is it router, or dhcpd service on linux, or the NAS you have?
