Let me summarize here the comments I've read so far and what we disussed
with Ilya on irc:
* btrfs check -- seems to be accepted
* btrfs restore -- seems to be accepted
* btrfs rescue
* select-super -- it is a command that can make
things bad and should be used with caution, thus not very suitable
to put under 'rescue' command, let's keep it as a standalone utitly
for now
* show-super +
* dump-super -- they do basically the same thing, the output is
different, Ilya suggests to keep only 'dump-super' with 2 output
modes, and I agree with him
* debug-tree -- suggested name is 'dump-tree'
Then, the namespace 'rescue' does not fit the purpose, these are
debugging commands, so the proposed name is 'debug'.
They do not seem to fit into 'inspect-internal' which is supposed to
work on a mounted filesystem, and I think this should contain commands
for infrequent but useful things.
Let's focus on the above commands for start, we can add more later (eg.
the repair subcommand).
thanks,
david
