I have no subvol=/ option at all:
Probably depends on kernel, but I presume missing subvol means the same
as subvol=/ .
I am only interested in mounted volumes.
If your initial path (/local/.backup/home) is a subvolume but it's not
itself present in /proc/mounts then it's probably mounted as a part some
higher-level subvolume, but this higher-level subvolume does not have to
be root. Do you need volume root or just some higher-level subvolume
that's mounted?
