Have you never used a Linux distro? I always end up with two windows managers, two login managers, 2-3 shells, 2-3 package managers and what not.

I want to see your 2-3 package managers :-) Unless you count apt, aptitude, apt-get etc separately.

One saving grace with Linux distros is that usually the maintainers package versions that are compatible with each other. So if you stay with the default repos things work.

But yeah once you install newer versions from non-distro repos it might be fine (e.g. git) or things will break in subtle ways.

This 30+ year linux user says you never have 2 or 3 different incompatible bash's.

You can have multiple different sh's, but you have to go out of your way to force them to be used. And evenn if you did, dash and ash and older versions of bash and sysv sh are a strict totally compatible subset of latest bash, and none ever has the problem of incompatible or missing modules or plugin library. Old scripts work in new bash.

The python to powershell comparison was valid. This false equivalence was not.

The fact that you can have 2 window managers is like having 2 mp3 players. It's not the critique at all.
