    systemd: ensure nfs-config service is re-run as needed.
    
    The nfs-config service translates distro-specific startup
    configuration into "environment" variable read and used
    by systemd unit files.
    
    Currently it is only run once, so subsequent changes to the
    distro-specific files do not take effect when an nfs service is
    restarted.
    
    If we change "RemainAfterExit=yes" to "RemainAfterExit=no" then the
    service will be restarted before any dependant service is started, so
    the environment file will always be up to date.
