++ * 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
