Serge probably had a different meaning of "administration" in mind than
you. He meant the kind of administration where you actively take
advantage of SELinux and confine your custom applications by writing MAC
policies for them. You do this by adding SELinux types, roles and rules.
If you find it too difficult, then don't do it. You can simply run your
application unconfined, while leaving at least all the usual daemons in
their confined domains.
But writing completely new SELinux policies is not what the vast majority
of administrators have a need to do (but if they do, they can start with
the SELinux Policy Generation GUI tool).
