	 * says the following about openlog and syslog:
	 * "LOG_USER
	 *  Messages generated by arbitrary processes.
	 *  This is the default facility identifier if none is specified."
	 *
	 * I believe glibc misinterpreted this text as "if openlog's
	 * third parameter is 0 (=LOG_KERN), treat it as LOG_USER".
	 * Whereas it was meant to say "if *syslog* is called with facility
	 * 0 in its 1st parameter without prior call to openlog, then perform
	 * implicit openlog(LOG_USER)".
	 *
	 * As a result of this, eh, feature, standard klogd was forced
	 * to open-code its own openlog and syslog implementation (!).
	 *
	 * Note that prohibiting openlog(LOG_KERN) on libc level does not
	 * add any security: any process can open a socket to "/dev/log"
	 * and write a string "<0>Voila, a LOG_KERN + LOG_EMERG message"
	 *
	 * Google code search tells me there is no widespread use of
	 * openlog("foo", 0, 0), thus fixing glibc won't break userspace.
	 *
	 * The bug against glibc was filed:
