If none specifed, '/var/lib/nfs/rpc_pipefs' uses by default. That path is as the process performing the mount sees it? > If no rpcmount mountoption, no rpc_pipefs was found at > '/var/lib/nfs/rpc_pipefs' and we are in init's mount namespace, we use > init_rpc_pipefs. It's the "we are in init's mount namespace" that I was wondering about. So if I naievely chroot, nfs mount stops working the way it did before I chrooted unless I do an extra setup step? I'm actually poking at getting nfs mount working in LXC containers with different network routing (mostly study so far, it took me a couple weeks just to get lxc to work for me and now I'm trying to wrap my head around Linux's NFS implementation), so I'm very interested in this...
