[gentoo-portage-dev] [PATCH 1/2] Support post-postinst QA checks

[Michał Górny]

Extend the QA check mechanics in Portage to support post-postinst QA
checks. They are like post-install QA checks, except they are run after
pkg_postinst(), and so they can be used to verify that necessary
postinst actions were performed (e.g. regenerating caches).
