Immutable distros works great when you want them exactly as they come. Anything else is a shit show IMHO.
As an example, multiple fedora based immutable distros dont have the codecs required to play YouTube videos. You have to either replace the rpm-ostree based Firefox with the flatpaks one or layer ffmpeg over the base system. Both solutions I wouldn’t expect someone without Linux knowledge to be able to do.
I’m still in a mechanical engineering world so just saying INT and FLOAT has people running away. Excel is the “safe zone” for them, sadly it means that I’ll just be doing the VBA part and oh gawd please get me out of here…
