So I'm thinking this the final nail in the coffin of the legacy interface
at least in rpc.nfsd. So if /proc/fs/nfsd filesystem is not or can not
be mounted then rpc.nfsd should fail... IMHO...

Maybe something like:

if (stat("/proc/fs/nfsd") < 0) {
    if (system("mount /proc/fs/nfsd") < 0) {
        xlog(L_ERROR, "Unable to mount /proc/fs/nfsd");
        exit 0;
    }
}

steved.
