Hi Matt, We're discussing building + distributing nfs-ganesha in centos-devel, https://lists.centos.org/pipermail/centos-devel/2018-December/017121.html Does it make sense to build nfs-ganesha V2.7 against Luminous's librgw and libcephfs, and then also allow users to install that build along with Nautilus' newer librgw and libcephfs? It sounds like this is what Gluster's doing with their ABI guarantees for libgfapi.so. The idea is that we'd always build against the "oldest supported" version of Ceph, but distribute it so that Luminous and Nautilus users would install the same libfsalrgw.so and libfsalceph.so binaries. - Ken
