IMHO distro specific things have no place in the makefiles or otherwise in your package. It should be assumed that you have a single or multiuser system and the admin wants to install the program system wide. This means only one binary is needed because it builds for the hardware on that system. Distro specific hacks are the problem of the distro and were not intended to be included in my rant, my concern of "no make install" was for the users. Things are just so much better in PATH... > Also, what should "make install" do if John the Ripper was not built for > system-wide install?

Although personally I can't imagine "pros" who really prefer having to "cd /john && ./john" instead of "john". Especially when you imagine the number of tools most of us have installed the whole idea of leaving every program in it's own dir because ridiculous. That said, your choice of defaults are completely up to you as long as we keep the systemwide stuff for those of use who don't build out own hierarchy of programs in our home dir. > That said, I might in fact add a "make install" in 1.8+.

I hope that the above helps, and I would be very happy to give my opinion (and help) on this goal to the best of my ability (and in a non-gentoo specific way. > > For Johnny (as it is), implementing "make install" should be trivial. Yes, yes it is. I just could not stop my jaw from dropping when it said "make install not tested". I kept thinking "then why on earth did you bother to write a "make install". Personally I like to test the things I write (and release).
