You see Russell, I wasn't too wrong on that (apologies again for
misspelling your first name). SELinux should not be considered. My
original message was posted on refpolicy and was only about policy
development ("this list").

I do not agree with you. MAC policy development requires knowledge of
the whole underlying OS including very silly details about location of
files (and including very silly details such as tiny differences in
different distributions). Developing SELinux userspace mostly requires
knowledge of libc, libselinux and friends (which have extensive
documentation as info and man pages as opposed to very short embedded
comments for interfaces in the .if files). Developing SELinux kernel is
probably something in between the two things when it comes to
difficulty, at least in my perception.
Writing C code is easier at least for me. And testing C code is easier
at least for me. For example the C compiler gives much more meaningful
warnings and messages. And you've got the debugger as well !
At the very least policy development is more tedious in my opinion.
But all of this is subject to personal attitudes and other similar
factors.

Guido
