Always tinkered with Linux, since eeeearly Red Hat days, but took the first full move when I set up my home lab and needed to host some docker containers with hardware pass-through.
Turned out my hardware was a bit too new for the kernel I had to install so ended up teaching myself a lot in terms trying to get everything to work.
Because of that I got quite comfortable on the terminal and from then, the UI suddenly made sense, because I understood better the concepts underneath.
Run three boxes with various versions of Linux now, a couple more if you count dual booting, a couple more if you count Mac as some kind of Frankenstein UNIX.
By the way?
