Briefly stated, you don't. Just like / is the top of a Unix style directory tree, the root subvolume is the top of a btrfs subvolume tree. You can't go higher than that, and that's what the top level /is/. But what are you actually trying to do? You _can_ change the default subvolume pointer so a subvolume other than root/5 is mounted by default, and you can nest subvolumes, so for most purposes, you can /pretend/ that some arbitrarily named subvolume is your top subvolume. Alternatively, you can of course mount subvolumes wherever you want in the directory tree. Also see the subvolumes discussion and related FAQs on the wiki if you haven't. https://btrfs.wiki.kernel.org/ -- Duncan - List replies preferred. No HTML msgs.
