RedHat 3.0, kernel 1.2, early 1996. I was a contract developer and took a job for a customer to update an in-house curses app on SCO Unix. Aside from a few lab uses in college, I had never used Unix before. I was like, welp, I’ll just install RedHat, do the work there, and recompile the app at the customer’s site on their SCO machine. Stupidly charged into a massive learning curve (unix vs linux, gmake vs make, gcc vs cc, ncurses vs curses, … none of which I had any familiarity with), but, amazingly, I got the job done! Kept RedHat as a second boot option on my workstation, and continued to use it more and more… 30 years later, I’m typing this on a MacBook Air running NixOS.

Slackware, to get away from the pink boys! Also there were only two or three distributions at the time.
Too many to remember since then.

(Hail Eris!)

Tried ubunto with mint about 10 years back. My first actual daily driver was endeavoros about 1.5 years ago and it has stuck!

Its either Ubuntu or Debian I cant remember

I think it was actually DBAN I dabbled with firstly, and then like you Knoppix. I played too much later with microkernel distros like DSL / Tinycore, then Debian / Ubuntu’s etc.

Red hat (in '99). I chose it because it was included on the disc that came with an IT magazine I bought at the time

I moved to Linux From Scratch a few years later, then to Debian. I have been on Debian based OSes since then, I like Mint at the moment

Knoppix was my favourite recovery and rescue live CD

Soft Landing Systems (SLS). So many disks!

BeOS ;)

I know, not Linux. But it was my first OS other than the one that came pre-installed.

Can’t remember exactly which was my very first Linux distro but probably Knoppix or another early live one.

My first “wipe Windows and install on bare metal” was PC-BSD. I know, again, not Linux.

And again, can’t remember exactly the very first “wipe Windows and install on bare metal” Linux, probably Puppy or Ubuntu.

Slackware on a whole lot of lettered floppy disks.

Suse 5 or 6. I think. Throw some Debian in there around that same time frame.

Debian. They mailed me the install media.

Mandrake 9.2 (before the Mandriva rebranding)

Raspbian Bullseye ARM32 -> Ubuntu 18.04/22.04 LTS -> Kubtuntu 22.04/24.04/25.04 (--minimal-install to avoid snap)

I had a machine with multiple OSes chosen at startup with OS/2 Boot Manager, including OS/2 Warp, Windows NT Workstation 4, and Redhat 5.0 which came on a CDROM labeled Pink Tie 5.0. (It was late '90s I guess. I used MSDOS before that. And a Commodore 64 before that) I believe I put a mail server on it (the Redhat partition) while I was still on dial-up (128K ISDN). The mails waited somewhere until I got online and signalled to send them to me. But then upgraded it to DSL. I was still running Redhat 7.3 with my mail server until 2006, even though Redhat 9 and Fedora were out by then. In 2006, I shut it down and bought a Windows 98 laptop to travel around Central America for a year. The Guatemalans laughed at my Windows 98 laptop–they were running Vista. When I got back to the US in 2007, and broke the laptop screen, oops, I bought a $300 desktop PC that had Lindows installed.

Early Mandriva with KDE 3.4 or 3.5 I think, but I can barely remember anything with clarity. It couldn’t have been bad though, since I haven’t used Windows on my own devices since 😉.

From my foggy memory, I think it was good for my then nocoder self, easy to use, stable, relatively lite, and had good looks.

I missed the Mandrake and pre-Fedora Red Hat era, but not by much.
