command line compatibility with the resolvconf(8) tool of various Linux
distributions and BSD systems. Some options supported by other implementations
are not supported and are ignored: -m, -u. Various options supported by other
implementations are not supported and will cause the invocation to fail: -I, -i,
-l, -R, -r, -v, -V, --enable-updates, --disable-updates, --updates-are-enabled.
