Why not make it default_user, default_role, default_type, and default_range? Creating an object doesn't really imply a transition, so "trans" seems misleading. > > > > I agree with Chris.

I don't like "parent" as a token either, and SELinux doesn't know > anything about processes and parents anyway.

Also, I don't see that you've addressed the issue of range/level defaults needing to specify whether you want to inherit the low level, the high level or the complete range of the source or the target contexts. -- Stephen Smalley National Security Agency -- This message was distributed to subscribers of the selinux mailing list.
