Thanks for the patch, and sorry for the slow response!  I took your idea
and tweaked it into an "early exec" daemon parameter that runs at the same
spot that your "bootstrap exec" ran.  My resulting version also has the
code for early & pre-xfer reorganized a bit into functions that both the
before-transfer execs can share, and I managed to fix a couple minor issues
that I noticed along the way (such as the RSYNC_PID environment variable
not matching between the pre & post exec funcs).
