The context is not the problem. I'm running the targeted policy from
FCdev, which makes both /bin/rpm and /usr/bin/apt*
system_u:object_r:bin_t. rpm works fine, however, whereas apt-get does
not.

I believe apt needs similar modifications. The attached patch to apt
fixes the problem for me. I'm not too familiar with rpm, apt, or selinux
internals, so this patch might need some work. I just took the code
from rpm's lib/rpminstall.c/rpmInstall() function which seemed to be
missing in apt's apt-pkg/rpm/rpmpm.cc/pkgRPMLibPM::Process() function.
Had a closer look and the patch indeed seems correct: applied, thanks!
