Initial rebuild and apply of our patches is promising.  After changing
from uuidmode: md5 to guid_mode: sha1 anyway!

The IO hit of running a 'reconstruct -g' annoys me somewhat - having to
rebuild the entire index file when all you want to do is zero the UUIDs.

I suspect I might write a "fast_zero_guids" tool, the effort involved
will pay for itself pretty quickly!  I might even do a "fast_sha1_guids"
tool, but that's a bit less useful since it still takes the IO hit.  The
only real advantage is being able to pre-calculate the sha1s and then
lock the mailbox just long enough to stream the index file.

I'll get back to you on these ideas!  Got a choir reheasal now.


P.S. is our patches against 2.3.10 now.
I haven't ported mismatcheduuids forwards yet, but that's the only thing
missing.  Everything else that's gone away is gone because it's already
upstream or obsolete now becase of other changes :)
