Sometimes 'sudo' is needed to be installed in /bin when /usr/bin is not yet accessible (like in sys-apps/hprofile - see linked bug). Had to patch the ebuild (with optional USE flag, patch following). BTW, is it worth not keeping this binaries in /bin?
Created attachment 148998 [details, diff] ebuild patch optionally (by USE flag "rootfs") installs binaries into /(s)bin instead of /usr/(s)bin
i'm not interested in shuffling a lot of binaries from /usr to / just to satisfy a random package
As Mike said.
