Hello ~wolfinthewoods,
I did come across nix, I find the concept intriguing, however I ended up with >50000 additional files under /nix in no time (1 hour maybe :) and since I'm striving for small systems (really hard these days), that kind of didn't cut it for me.
A system without perl and python and php and ruby and nodejs ... can be installed. I succeeded with alpinelinux. But then, how useful is this for me as a daily driver? Hmmmm. I can do quite a bit. But perl comes back with my own scripting, python comes back in with borgbackup, and emacs needs a bit of space to accomodate my 2 dozen extra packages ... and then I'm back to a not so small system again. AGAIN! Ah, and I use Gimp, KiCAD, LaTex once in a lengthy while, but that takes quite a toll.
~bartender? You have some herbal tea to convince my brain that it is not really needed to do another round of "small"? Sigh. No? Hmmm. Maybe some hot chocolate with spices. It's this time of the year again. It's well past noon and the fog has not lifted ...
Cheers!
