For bidirectional sync I prefer unison. If there exists any dist not having unison on their repos i dont know...

By the way, is it ok the version for you? I mean in debian jessie is still the 2.40 (i guess there will be soon a backport), but i can compile 2.40 if it is needed (2.46 changed something and you can not use 2.40 with 2.48)

about the openrepos i will see how to create the rpm and how it works, but probably it will be once my jolla phone arrives!!!
