In practice we have to extensively customise policy long before getting to the
non-proc stage of optimising for small hardware. The Familiar distribution
(used on the iPaQ) has /proc but needs significant policy changes when
compared to a typical Fedora workstation. Not only is there the issue that
embedded distributions have different daemons and path names to workstations,
but the memory constraints mean that even a modular targeted policy is not as
small as you desire.

I think that is the correct thing to do. Someone who is prepared to do all
the work needed to get a recent SE Linux system operating without /proc will
have no problem changing the kernel config scripts and everyone else would be
better off not being confused by being offered sets of options that are not
viable.
