I've been asked by FESCo to post this public service announcement :)
We'd just like to remind those who test Fedora, in whatever way...running a stable release with updates-testing, running Rawhide, being a proven tester (especially)...that it's best if you test with SELinux enabled and enforcing. This is the default configuration of Fedora, so we need testers to be running with this configuration so we don't miss problems that show up when SELinux is running.
For proven testers, I actually added a section about this to the instructions recently - https://fedoraproject.org/wiki/Proven_tester#Testing_process .
We recognize there may be situations when SELinux causes problems and you need to make it permissive or turn it off temporarily, but please try and keep it turned on if you possibly can, and if you're in a situation where you need to disable it, please let the developers know by filing a bug, so they can fix it and you can turn it back on. Thanks a lot!
