Note that these were added to /usr because that's where they exist on NetBSD, OpenBSD, Solaris and Linux. So we're not just talking about hardcoded-paths in a few scripts that FreeBSD users might have written for use only on FreeBSD. So, I expect we will want symlinks to remain in /usr, forever, if we move the programs to /bin. (Moving them does seem reasonable to me. I'm just saying why they were put in /usr in the first place...) -- Garance Alistair Drosehn = drosehn@rpi.edu Senior Systems Programmer or gad@FreeBSD.org Rensselaer Polytechnic Institute; Troy, NY; USA
