Thanks for the hint. However, I couldn't use the --rsync-path option:
there is no error message, but the option is not taken into account.
I have copied the rsync-debug script, and it isn't called. I tried to
provide an invalid path, and there was still no error.

Maybe it is because the remote machine is also the local one?

With this option, the behavior (seems to) change: after a few seconds,
rsync keeps printing
[generator] make_file(usr/bin/head,*,2)
for several minutes at least (until I stop it)

What could make the generator loop over the same file?

Thanks
