Slackware was my first as well. You really learned Linux using it. I probably rebuilt that drive a dozen times because I’d bork something and it was easier to reinstall than it was to figure out how I broke it in some new novel way.
Also not having a phone to look stuff up and having to rely on looking stuff up in books was hell now that I think of it.
Having the phone these days for reference is huge. When I did my current arch install a few years back, I realized how clutch it was having that option because it definitely wasn't a thing even back in the mid aughts. Sifting through even the console manual was tedious as opposed to just searching for a solution, it makes one grateful for the current state of things.
That was a reason back then to pay for a distribution box - it came with a very good printed manual. Which had beginner friendly sections like "now that you have a running system let's configure and build a kernel matching your hardware".
Same, Slackware, went over to Red Hate for a while then Debian - am using Ubuntu now. I'll never forget (in 1998) setting up Slackware as a server on an old spare 486 the company I worked for had laying around. It had a SCSI hard drive. Oh the pain. USENET was the only good reference, and you'd sometimes have to post and wait a day for a response if you just couldn't figure it out.
Got that server running and saved the company hundreds of dollars a month - they had been paying egregious fees to host brochureware. They thought I was Superman.
