i think we really need to have stacked LSM's, because there is a large set
of people who will never use SELinux. Every few years, I take another
look at SELinux, my head explodes with the (IMHO unneeded complexity),
and I go away again...
Yet I would really like a number of features such as this ptrace scope idea ---
which I think is a useful feature, and it may be that stacking is the only
way we can resolve this debate. The SELinux people will never believe that
their system is too complicated, and I don't like using things that are impossible
for me to understand or configure, and that doesn't seem likely to change anytime
in the near future.
I mean, even IPSEC RFC's are easier for me to understand, and that's saying
a lot...
