attempting to restructure my fs snapshots the proper way, previous way
was like this:
(subvol=0)
boot
etc
var
...
SNAPSHOTS/01-16-14/{boot,etc,dev, proc..}
SNAPSHOTS/03-22-14... etc
i removed all but the 01-16-14 via sub del. i then thought 'i don't
want the data at top-level anyways as its a botched upgrade, so i'll
just revert to the last snapshot via a mv.
so i rm'd everything at top level except snapshots, cd
snapshots/01-16-14;mv * ../..
now an ls -a at the dated dir shows empty, my files are where they
should be so i really just want this to be gone. and a sub list on the
top-level mount path lists:
# btrfs sub list -ta /mnt/1
ID gen top level path
-- --- --------- ----
291 199502 5 SNAPSHOTS/01-16-14
yet, oddly enough btrfs sub del really doesn't want to delete it, even
though it's entirely empty and not in use either.
# btrfs sub del /mnt/1/SNAPSHOTS/01-16-14
Transaction commit: none (default)
