The bug seems to affect CentOS 5.2 too, so perhaps it should occur in RHEL too. I can't see a code path that works in quite the same way for RHEL-5.2. It may adjust the system wide configuration file when run directly by root, but I don't see that it will when run from CUPS. Are you seeing AVC messages on CentOS 5.2? FWIW, the way I was able to trigger the AVC message on Fedora 10 was by switching on a connected USB HP printer; this triggers hal_lpadmin (running in cups_config_t), which in turn runs hp-info (running in hplip_t). That's precisely how I found the AVC. I had installed F10 for awhile, but never started the printer. After switching hplip.conf_t domain in permissive to make sure the AVC's still appear, then ausearch -m avc -ts today | audit2allow -M myhplip; semodule -i myhplip.pp (because it was the only denial I had on F10) After a major power outage last night, I fired up CentOS 5.2, applied the updates and I start browsing Setroubleshooter. I noticed this kind of denial but at the moment the net was still down so I couldn't report anything. I'll reboot in a few hours, test it again for AVC's and if any I'll report back here. hplip-2.8.12-5.fc10 has been pushed to the Fedora 10 testing repository.
