I think the errors that rsync complains about on devices and fifos should be
ignored. I applied this patch and the errors go away and the backup-bouncer
test succeeds (e.g. the fifos and devices are recreated without error):

I'm getting the same error with pre8 and the nightly from the 27th. I
haven't boiled it down to a reproducible case yet, though. I tried to do
that last night but ran out of time...

I don't know. Somtimes it works and sometimes not (but mostly not as a rule
of thumb). Even if I wait for a few minutes inbetween, the new file won't be
chosen.

rsync version 2.6.3 protocol version 28
That might be old, but that was the default that came with fink on Mac OS X (if
the error has been fixed in the meantime, I will upgrade).

Duh. I realize now that it's perfectly reasonable for you to be able to
reproduce the problem while I can't. Versions 2.6.9 and earlier of rsync
sort the file-list using the C library's quicksort, an unstable sort, ???so
the results in case of duplicate files are highly sensitive to both the C
library implementation and the order of directory entries in the source (which
in turn is sensitive to the filesystem implementation). You probably have both
a different C library and a different filesystem than I do.
In any case, since rsync 3.0.0pre1, the default file-list sorting algorithm is a
mergesort, which is stable, so files from earlier source arguments take
priority. If you upgrade to an rsync 3.0.0pre* version, your scenario should
work consistently. If it doesn't, that's a bug we should try to fix.

Oh, thanks a lot for the explanation :)
I will try to figure out how to build it and test then.
In this particular case it is not needed, but what about a switch:
--always-take-the-latest-file-version-no-matter-of-order-of-supplied-arguments
?
Two problems still remain then: one is that I cannot rely on the fact that users
will have the latest version (at least for a while, but that argument will
disapear with time), and the other one - it would simplify the work a lot if I
didn't have to reproduce a bunch of empty folders in "new" (for
which you have said: "I agree that this feature is useful, and I might
implement it at some point as a patch.")
But thanks a lot for the explanation. You just gave me a really nice idea for a
real-life task for the forthcomming informatics competition here :)
