The top level of the filesystem is itself a subvolume, so you could just leave it like that. Alternatively, if you want the top level to be simply a container for subvolumes (and to use a default subvolume to mount / ), then you could do the switch-over by making a snapshot of your current /, remounting with the snapshot as / (possibly using "btrfs sub set-default"), and then mounting subvolid=0 on /media/btrfs-management to delete the old contents of / (I hope that made sense) Hugo. -- === Hugo Mills: hugo@... carfax.org.uk | darksatanic.net | lug.org.uk === PGP key: 515C238D from wwwkeys.eu.pgp.net or http://www.carfax.org.uk --- "He's a nutcase, you know.
