Through my (short) job experience to date, I have gained quite a bit of knowledge of how SELinux works, from an implementation point of view and how to administer it.
I personally have several qualms with SELinux, such as it seems to be overly complicated in many regards to the point that security seems to be very hard to reason about. So, I'd like to know how warm the industry is to SELinux.
Do you employ SELinux on one of your production servers? If so, what kind of success do you have? No seriously divulging details, but do you work for an organization that is involved with Government, (DoD/DoJ, defence contractor, etc)? Are there non-government companies that find this useful?
