Hello
When I'm trying to install my favorites services on banana pi, I saw some packages missing from C7 pre-alpha repo.
So I have compiled some packages on the BPi, using sources downloaded on my Centos7 x86_64.
Actually I've compiled missing packages to install pcs (cluster system) : - corosync* - pacemaker* - sdb
My repo is actually behind a low connection (above 1MB/s in upload), so it can't be use by all, but you can access it if you want to get the packages and add them to c7 armdev repos.

I will add others packages in the future. Nicolas Repentin
