With btrfs you create subvolumes within the same master volume. The default is to have separate subvolumes for / and /home. When doing a new install you can create a new / with a new subvolume name within the same btrfs file system. rootfs-22 instead of just root for example. That way you can mount your old / as a subdirectory while moving over all your config to the new /, and you can keep the same /home. When you are done, delete the old / subvolume and you get your space back without any repartitioning. look at the subvol=XXX in /etc/fstab If you want to back up and restore individual subvolumes, look at the btrfs send and btrfs receive commands. on., 06.05.2015 kl. 09.08 -0400, skrev Neal Becker: > Actually, re-partioning old machine. > > Last time, I setup 1 big 1TB btrfs partition.
