Background
Karsten 'quaid' Wade gave a keynote at Southern California Linux Expo 8x in January 2010. The talk was called Being a Catalyst in Communities - the Scientific Facts About the Open Source Way. The talk discussed lessons learned from open source product launches. Two projects were cited as being less popular upon launch: 1. Fedora and 2. SELinux. While Fedora has impressive market share growth, SELinux continues to have a less than popular public opinion. Someone from the audience said, "you have a marketing problem," when it comes to SeLinux. We agree.
Later that year, Dan Walsh gave several talks at SouthEast LinuxFest on SeLinux (when klaatu uploads the videos to archive.org , we will link here.) There he theorized that because the SELinux "disable rate" was high on Red Hat Enterprise Linux products but not on the Fedora product, SELinux's unpopularity issues persist in the system administrator community.
Myths
1. SELinux is a Red Hat/Fedora specific product.
2. SELinux is not Free Software.
3. No good documentation exists for SELinux.
4. SELinux is at least as complicated, if not more complicated, as it was x years ago.
5. SELinux is only for customers in the United States government.
6. If I do not turn off SELinux then I will be blocked out of my own desktop.
7. I run several virtual machines but I think SELinux is overkill for securing my hyper-visor.
8. SELinux does not have a GUI... even if it does, it will not be powerful.
