So, I did read the entire wiki, but it's been a while, and either some
things got added since then, or some I just didn't remember because I didn't
need them at the time.
The problem, and we've talked about this before (my plea to make btrfsck put
a "--really-I-read-the-wiki-and-want-this" :) option as well as minimal
instructions in its usage that tell the unsuspecting user it's not what
they're looking for, here too, I carefully re-read the man page for btrfs
and this wasn't mentioned in it, or at least in my copy.
Out of sync docs happens, but I'm hopeful that the man page and tools --help
info can be the canonical place for info, even if they can point to a wiki
link since the average admin will always fail back to --help/--usage and the
man page first before looking for a missing option in a wiki somewhere else.
Does that sound reasonable?
