"secure" is an meaningless term without reference to a deployment
model and threat model, but let's assume here for reference that what
you mean is that the shipped RPMs should be configured to not grant
any additional privileges over that afforded to the traditional Unix
timesharing model, and then the desktop kickstart modifies them.

I would agree with that, but it's not trivial.  Are we just scoping in
PackageKit here, or also consolehelper @console actions?  Does it
imply removing the setuid bit from /bin/ping?

See "man PolicyKit.conf"
