Talk:BTRFS Fun

About this Adrien,

# mkdir /live-root
# mount -o subvolid=0 /dev/sda4 /live-root
# rsync -aHA --exclude="/live-root" / /live-root

If you had install your Funtoo box inside a subvolume....

For exemple :

Subvolid=0
  ----> @root id=255 or any number

You would be able to use this instead :

# mkdir /live-root
# mount -o subvolid=0 /dev/sda4 /live-root
# cd /live-root
# btrfs subvolume snapshot @root @live-root

I think that you should add something about installing a Funtoo inside a subvolume instead of installing it directly inside the subvolid=0
