++	 * glibc problem: for some reason, glibc changes LOG_KERN to LOG_USER
++	 * above. The logic behind this is that standard
++	 * http://pubs.opengroup.org/onlinepubs/9699919799/functions/syslog.html
++	 * 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:
++	 * bugzilla.redhat.com/show_bug.cgi?id=547000
