I was aware that AppArmor work is going on in Debian and this is good.
And I agree that most of such work should be done as far upstream as
possible.

I will not debate against AppArmor or try to promote SELinux against
it here. Those working on such software know about the advantages and
disadvantages of the different approaches.

Here is some current information about SELinux in Debian:

I can not commit to that, but I will see what I can do regarding
initial work. I already had a bit of practice with the Tails build
process. Ideally maintenance will mostly be done upstream - including
policy maintenance.

SELinux requires xattr-support. According to this page SquashFS
supports xattr since Linux 2.6.35, so that should work with a current
kernel version (but I have not yet tried):
