Slackware, installed with floppies on a 486.I tried debian red hat suse coral linux but always came back to Slackware.There was a bunch more, that I cant remember the names of, one I do remember was Stampede linux, Daniel Robbins put it out, he then dumped it and made Gentoo, I used Gentoo for a year or so, on an original AMD Athlon, it was night and day different from un optimised Slackware. I saw an announcement for a new distro on the gentoo forums for Arch, 686 optimisations, no need to compile!. I installed that and used it for about 9 years. I got sick of all the breakages, the systemd adoption drama, briefly went back to Gentoo( or Funtoo, actually), then discovered Void. I have been using Void since 2010, I also use Openbsd, reminds me of the 'old days' of linux before the tech bros and corporations.
Ha! I remember Funttoo. Was that the one that vowed to be completely open source everything? I was so pumped for that distro but then I checked back a year later and it was partnering or doing something with BIG Closed Source megacompany. I was like, "what the hell!". I really had high hopes for that guy and his endeavor. I might be thinking about something else. But after that, I was die-hard crunchbang as my daily driver. That thing was smooth until Philip put it to a close.
