Is it? OK, any idea what caused that and how to fix it?
I can't find much on Google about it except this page:
says "The init process then runs /etc/rc.d/rc.sysinit, which is labeled
initrc_exec_t. The kernel has a rule that says when init_t execs
initrc_exec_t it transitions to initrc_t. So this continues until the
httpd executable gets started as httpd_t." Even though in my case it's
