The "Install-Same-As" header on that page looks ideal for this case. The bootstrap issue would certainly need a solution, but it doesn't seem too hard to have an option/configuration to ignore such dependencies. Someone installing a specialized build chroot might want that options as well. For instance, a build chroot could install an /etc/apt/apt.conf.d/* file containing: Ignore-Install-Same-As: libc6, libpam0g I think that largely addresses the other cons as well. Do you know if anyone has looked into what it would take to implement Install-Same-As in apt? - Josh Triplett
