commit 77f7556878d1fe03dc3e285c97dd822db38f618c

    Due to an installation mistake (somehow rpm messed up) I ended up with an passwd
    file which didn't have a rpc entry.  This meant that during startup the
    getpwnam() call to determine the details for user rpc caused the normal process
    for passwd lookups to be followed.  For me this meant after looking at
    /etc/passwd the lookup tried to use NIS.  This of course deadlocked since as
    part of the NIS lookup rpcbind has to be contacted.
    
    The workaround is quite simple: use __nss_configure_lookup() to restrict
    the lookup.
