↳ In-reply-to » @lyse @tftp Someone has pointed out that there’s OpenRsync:

Actually, I’m stupid: I’m using the normal rsync on OpenBSD as well.

And regarding OpenRsync’s general usability:

Right now openrsync is limited in functionality and is primarily present
for rpki-client. The limited functionality makes it unusable for generic
use and so any diff or change like the above will not be considered since it
is simply not ready.

First problem to solve is to remove the mmap usage in openrsync. After
that modern protocol versions need to be added. Once that is in place one
can start a discussion about using openrsync as a default on OpenBSD.
