I agree with you that we would currently have to allow pretty much any
access by apt_script_t, unfortunately. Sorry for mixing up apt and dpkg
again in that post btw, yes, it sould be dpkg_t and dpkg_script_t,
obviously.
No, I can't really think of ways to restrict dpkg_script_t apart from
not messing with the dpkg_t state files. Maybe we could make some policy
that /usr is to be modified by dpkg_t only whereas dynamically generated
files have to reside in /var, but I doubt this would currently hold.
And after all, dpkg_script_t needs to be able to even add users
to /etc/passwd (although through the helper applications, not directly).
best regards,
Erich Schubert
