The following works for me.
sudo mkdir mnt sudo mount -o subvol=@ /dev/sdb1 mnt for i in dev dev/pts sys proc run; do sudo mount --bind /$i mnt/$i; done sudo chroot mnt
Is it possible to include btrfs or to build it seperately, if it's not already included in
chrootuid fakechroot schroot
should be included.
If everything doesn't work, who will build me a nice, secure script?
