Re: [PATCH 05/23] fsmonitor--daemon: add a built-in fsmonitor daemon

I think these compile-time macros should be replaced with a
method call, as I've said before. It should be simple to say

	if (!fsmonitor_ipc__is_supported())
		die(_("fsmonitor--daemon is not supported on this platform"));

and call it a day. This can be done before parsing arguments.

+int cmd_fsmonitor__daemon(int argc, const char **argv, const char *prefix)
+{
+	enum daemon_mode {
+		UNDEFINED_MODE,
+	} mode = UNDEFINED_MODE;
+
+	struct option options[] = {
+		OPT_END()
+	};

I can see where you are going here, to use the parse-opts API
to get your "--<verb>" arguments to populate an 'enum'. However,
it seems like you will run into the problem where a user enters
multiple such arguments and you lose the information as the
parser overwrites 'mode' here.

Better to use a positional argument and drop the "--" prefix,
in my opinion.
