Recently Debian has started to transition away from the "which" command. [1]
which is a non-POSIX command which prints out the location of specified executables that are in your path. Unfortunately, there are several versions of the program around which are not compatible with each other. We package the GNU version as sys-apps/which, which is in the system set since 2004. Already in 2007, vapier asked developers to avoid which in ebuilds. [2] The replacement in most circumstances is "type -p" which is a bash builtin command. So, should we join the "which hunt", with the goal of removing sys-apps/which from the system set and from stage1? I think the first step would be to identify which packages use which, and add it as an explicit dependency. (Maybe the tinderbox could help there?) A bug for this [3] has already been filed by mgorny some time ago. Unfortunately, the command pops up in unexpected places, e.g. it appears to be an (indirect) build-time dependency of systemd.
