I've apparently forgotten whatever little I may have known about
setting up nfs from having used it long ago.
I found a brief help page on google that I used to get this far along
at:
http://linux-bsd-sharing.blogspot.com/2008/09/howto-setup-nfs-server-on-gentoo.html
Its very brief and has no debugging info.
Also I see nothing about debugging in /etc/conf.d/nfs either.
After setting all nfs related kernel items and booting the kernel.
(The setting are inlined toward the end of this message)
Checking that mods appears to be installed and running. Making sure
portmapper is running.
Then when I try to start nfsd service it fails, producing these
messages in sysklogd:
Jan [...] nfsd[29077]: nfssvc: Protocol not supported
Jan [...' : RPC: failed to contact local rpcbind server (errno 5).
Hm, maybe it's the portmap version:
Only one of the nfssvc lines appear but the RPC line appears several
times.
I got the impression from google that nfssvc was related to nfs4 so
may not mean too much ... but then I'm really not sure what it might
mean.
I don't really know what info would be helpfull but have included
output from emerge, rpcinfo, lsmod and related kernel settings:
Installed nfs related pkgs

From the config help test: "If you enable this option, you must run a
portmapper daemon that supports rpcbind protocol version 4."
Chuck, what's the minimum userland required to support this?
User land must be running a portmapper that supports rpcbind protocol
version 4. Currently Linux's portmapper does not, which is why the
setting defaults to N. Recent Fedora distributions have replaced the
portmap daemon with a port of Sun's rpcbind daemon, which does support
rpcbind version 4. But most other distributions still use portmap.
I was hoping not to clutter svc_register() with logic to determine
which is running, since it will add complexity with little value. And
eventually (or, soon, hopefully) everyone will run the rpcbind port,
and that logic won't be needed at all.
In addition, rpcbind/libtirpc are still not entirely stable (API/ABI-
wise) so it may be better to leave this as a hard compile-time switch
until distributions are comfortable replacing portmap with rpcbind.
