Re: Security contexts for the contexts directory?

With the new design of the policy tree, we have moved the

These files include default_contexts, file_contexts, default_type,

as well as contexts for individual users like users/root. Currently the
security contexts for these files is etc_t. Should we change them so
something else? default_contexts_t? Should file_contexts be marked
differently then the others?
I'd suggest a single type (other than etc_t) for default_contexts,
default_type, failsafe_context, and the other files installed from
policy/appconfig. file_contexts should likely have a different type to
allow different access, so perhaps it should have its own directory and
type. With the old layout and policy, it ends up in policy_config_t,
but I think we want to distinguish it from the binary policy file as
well as from the appconfig files.
Also since policy is determined by /etc/sysconfig/selinux, should we
set
a special security context on it? If we do should we move it to a
directory where it would be easier to maintain the security context?
Maybe rename it to /etc/selinux/config?
I would prefer having a distinct type on it (and moving it to a
directory with that type so that we can easily preserve the type), as
the integrity of that file is critical to SELinux, at least in the
Fedora Core implementation.
