Hey, I'm not exactly new to portage, but one thing that I cannot seem to figure out is how to rebuild all dependants of a package. Not *dependencies*, dependants: packages that require said package.
As a recent example: whenever go (the language) is updated to a new version (say from 1.9 to 1.10, as it happended recently), I'd like to rebuild docker & friends - or more specifically 'things that are compiled with go'. The --changed-deps option doesn't seem to do the trick, so instead I manually do a -vp --depclean on go and manually --oneshot all installed packages that have their hands on it. This is obviously stupid and error-prone. Am I missing something or is this really not easily possible? Basically I'm looking for a hard --oneshot --revdep-rebuild with a package argument. thanks, Holger
