That's my next test, but I've used sysrescd to set up btrfs before, so I doubt that's the cause. > Also, which kernel version? 4.1.30 - then I realised that sysrescd defaults to an older kernel (my rescue version in /boot always boots to the alt kernel). I tried the alt kernel, which is 4.4.17, and it worked! Many thanks, Joost. It always helps to have someone point out the one obvious point I've overlooked! -- Neil Bothwick I am Ken Dodd of the Borg... What a fine day to be assimilated missus!!
