Matt,
Thanks. I'll take a look at this starting next week. I do realize
this is very risky. ;)
The other option I thought of was to only do the move when the mtime,
size, and filename match. Not really a 'detect-renamed' but a
'detected-moved' type operation.

I've started testing the detect-renamed patch with 2.6.9 and soon
3.0.0pre1. I have an unique situation where I'm rsync'ing to a
HSM based filesystem. I've found that the detect-renamed patch
works but it appears to do a copy of the file to the new
destination. This is particular slow since the file in the HSM
based filesystem may only be a stub and all the data is only
resident on tape. The copy waits for the datq to be recalled from
tape which depending on the file size can take a long time. I've
looked through the patch code and am wondering if there is an easy
way to have rsync do a move from the ~.tmp. directory.
This is easy to do, and I have implemented a --trust-detect-renamed
option to do it in the attached patch to the current CVS rsync.
However, it is risky because a false rename detection could cause
rsync to substitute an unrelated but similar-looking destination file
for a new source file. Don't use the option unless you are prepared
for the consequences.
