I hit upon a lot of pebkac errors.
... Though, in hindsight, maybe some of the determinations of "pebkac error" may have been a bit gaslighty darvo to hide bugs anywhere in the stack including up to ux. "you didn't read the , so it's your fault" type of events. ... reminds of the post-it note that's there to save the world, then eventually it gets ignored, then eventually falls away, gets crumpled, dumped, forgotten...

This is true. (always had installer, problems from haste & not reading).
It's like I was fine reading to do the installation, but it was like then I was done reading, for the ongoing management. This does indeed make the pebkac errors inevitable sooner. ... :/ I think, I see, why I read in gentoo, but didnt bother so much in arch... it's not just the colours... it's the pace. [Too easy to succumb to how, once past the installation, under use] Arch gets you accustomed to "now!" (/impatience). At least compared to old pre-binhost gentoo on older hardware.
Oh, and...
Restoring old gentoos to new is one of my fave geeky (~ and typically pointless) projects to undertake. ... Not sure I've done one as old as 6 years yet... but I do have one that's something like 16 years old. LOL. ... When I amass the spoons for such an undertaking, I may attempt.
