Hmm,perhaps I should mention that I use a modded version of Kernel Adiutor.How can SELinux be changed in Kernel Adiutor? Haven't found that option?
Perhaps its not in the "standard" version. It's under "Misc controls" in the modded version though.
You can also use synapse as I've added synapse support to the kernel. However, many things are still not setup, but setting SELinux will work.
