With strict/enforcing, I get the following avcs at bootup. Looks like rhgb does not 'run'; I get a text-style boot display.
Jul 21 10:47:52 fedora kernel: audit(1090406834.263:0): avc: denied { mounton } for pid=533 exe=/usr/bin/rhgb path=/initrd dev=ram0 ino=2 scontext=system_u:system_r:rhgb_t tcontext=system_u:object_r:file_t tclass=dir
Jul 21 10:47:52 fedora kernel: audit(1090406834.263:0): avc: denied { sys_admin } for pid=533 exe=/usr/bin/rhgb capability=21 scontext=system_u:system_r:rhgb_t tcontext=system_u:system_r:rhgb_t tclass=capability
audit2allow on this yields: allow rhgb_t file_t:dir { mounton }; allow rhgb_t rhgb_t:capability { sys_admin };
but this seems a bit too 'heavy'.....
