Is rpc_pipefs really needed for svcgssd? or just for 'gssd' and
'idmapd'.
I gather that a SIGHUP to idmapd will cause it to open the serve
channels after they have been made available. It is also sufficient
to SIGHUP idmapd after mounting rpc_pipefs if rpc_pipefs is mounted
later for some reason?
Thanks,

rpc_pipefs is not currently used in svcgssd.

The short answer is no. The current sighup processing in idmapd only
attempts to open/reopen the server channels. (Probably only because
the "normal" system starts the NFS client first, and then the NFS
server.)
It is possible to start two instances of idmapd -- one servicing only
the client, and one servicing only the server.
