People are boasting about Arch, but my first open-source OS was FreeBSD 4.2, fitting on a single CD-ROM. It included a tiny base system and C compiler, and practically every other package had to be compiled from source, using the ‘ports’ system, which was just a collection of makefiles, one for each package. And you had to be careful to use gmake instead of make, because the default Make was BSD-specific tool incompatible with most of open-source software, which targeted Linux. And you had to make sure to use GNU versions of grep, sed, and awk, and remove all bashisms from shell scripts, because /bin/sh was of course incompatible with bash. Package manager? What package manager? Just run suand then make install. And my PC was AMD K6, and it had Turbo button, which did absolutely nothing. And I was very proud of my TEAC CD drive.
