[PATCH RFC 0/2] nfsdctl: new nfs-utils tool for managing the kernel NFS server

[Jeff Layton <jlayton@kernel.org>]

With Lorenzo's addition [1] of new kernel netlink interfaces, it's a
good time to revisit how the kernel server is managed from userland.

This series first adds Lorenzo's original userland nfsdctl tool to the
nfs-utils tree, and then converts it to a subcommand-based interface, in
the spirit of tools like nmcli or virsh.

This is not quite at feature parity with rpc.nfsd(8) yet, at least as
far as autostart supporting options in /etc/nfs.conf. We need a way to
set the grace-time and lease-time. This also lacks a manpage and a lot
of needed --help text, so it's not ready for merge yet.

Consider this a request for early feedback: Does this seem like a
reasonable approach for managing the server?
