You know, immutable enterprise systems.
I installed HeliumOS (Almalinux bootc) on a corebooted Chromebook. Works really well, but audio needs to be configured.
The script needs a recent python which is not available there.
Go and rust can be installed for a user only. Is there something similar for python?
If you can install nix (you can install it per user) then you can have whatever you want in a temporary shell with nix-shell -p python
nix profile install nixpkgs#python if you want it actually installed
Home manager is also entirely user level I believe and lets you use a declarative config too
Home-manager > nix profile
Also, nix-shell is supposed to be used for debugging, and nix shell/run/develop for using packages without installing them
