[NFS-Ganesha-Devel] Re: Run multiple instances of NFSv4 server on same host / proper use of NFS_CORE_PARAM NFS_Program

I am investigating the option of running nfs-ganesha in an
unprivileged
user/mount namespace on Linux, to export some directory only visible
there, in addition to a main NFS server on the same host. It should be
a simple world-readable share, no security considerations client-side.

This seems to imply that the client hardcodes program 100003. I
don't
see an option for that in nfs(5). Could it be that a simple
modification in mount.nfs to add an option for the RPC program to call
would enable multiple instances of NFSv4 servers on one system, and
that right now the presense of NFS_Program in ganesha config doesn't
serve a purpose, at least with Linux kernel clients?
Anyone with a comment on that? Is it that strange to try to separate
(say, containerize) NFS server instances with Ganesha?
Am I in the wrong place for such user questions — the other mailing
list seemingly dead?
It looks like I'll not use NFS-Ganesha at all in the end, but it would
be nice to have a confirmation about the technical reasons why the
attempt to isolate NFS serving of a FUSE mount in a unprivileged
namespace has to fail … or how it could work instead.
Alrighty then,
Thomas
