Not how I'd recommend doing it. I'd say: # btrfs sub crea root # btrfs sub crea var # btrfs sub crea home Then fstab: LABEL=myfs / btrfs subvol=root 0 0 LABEL=myfs /var btrfs subvol=var 0 0 LABEL=myfs /home btrfs subvol=home 0 0 And finally, add this to your kernel command line in the bootloader to specify how to mount root: rootflags=subvol=root Hugo. -- Hugo Mills | The trouble with you, Ibid, is you think you know hugo@... carfax.org.uk | everything. http://carfax.org.uk/ | PGP: E2AB1DE4 |
