Re: [gentoo-portage-dev] [PATCH] emerge: add --changed-deps-report option (bug 645780)

[Michael Orlitzky]

Since ::gentoo is the only repository governed by the PMS, can't we make
repoman do this? The problem with requiring "repoman --force" for an
in-place dependency change is that repoman generally won't have access
to the unedited ebuild; but for ::gentoo, we can probably hack something
together in git. Have it source the old and new ebuilds, and compare
their dependency lists.

It won't work outside of a git repo, but it will work in the one place
that really matters.
