I hate to be a broken record :) but telling people they should read/have
read a wiki when they are in the middle of fixing a filesystem is not
the right way to go.
On my laptop while travelling, it would even be my only way to boot and
maybe I can't get to the internet until my FS is fixed (maybe, maybe
not, but you get the idea).
My main point again (sorry) is still that the man page and usage info of btrfsck
should really warn users "this is likely NOT what you want to run,
please read the manpage, or HOWTO in /usr/share/doc/ with details about
mount recovery and other things to try first".
Think of it as a good thing, it means more btrfs users, and they are
used to working a certain way. It's for btrfs to adapt to how they're
used to working when possible.
