Subject: [PATCH] btrfs-progs: btrfs.8.in: Add info about reverting back to root subvolume.
Date: Wed, 11 Sep 2013 14:34:05 +0530 [thread overview]
Message-ID: <2061327.l3bBKU3J9X@localhost.localdomain> (raw)
'btrfs subvolume list <path>' does not list the root subvolume's ID.
Hence there is no way for the user to set the root subvolume as the
default subvolume unless he knows about the magic number 5 (i.e.
BTRFS_FS_TREE_OBJECTID).
