Qubes OS 4.2.0-rc1 is available for testing

Hello, I would like to ask you more about SELinux, I cannot find answers anywhere else so please forgive me if I am using wrong thread.

  • Why will be SELinux only in Fedora templates?
  • Will it be in enforced mode or just installed?
  • Why developer choose to use SELinux right now? Sure it is one of best security feature but why it matters if you have disp netvm and why it is important now? Which threads it should be dealing with (i custom Qubes security architecture)?
  • SELinux could broke many other stuff in VMs, what custom setting and rules are prepared by Qubes devs team?

Thank you
