Unfortunately there is no correct answer here as we didn't consider this scenario when planning EAPI 7. We should have looked at Exherbo, which does make this important distinction. There is a bug report open. https://bugs.gentoo.org/660306 What I will say is that we should not attempt to executing anything from within ROOT or SYSROOT unless it known to be interpreted (e.g. a shell script) and there is no feasible alternative. I add that exclusion clause because I have been forced to do this with python-config. -- James Le Cuirot (chewi) Gentoo Linux Developer
