I have 702 paths in /nix/store which contain the string "python2"
Can you tell me how to check properly whether I need python2
support/packages? I'm not so familiar with the python infrastructure.
I believe a lot of the "python2*" packages will be python libraries that
are dependencies, so I would suspect that a vast minority would actually
be the CPython interpreter.
For determining what needs those paths you can use the nix-store --query
(-q) to find out. I'm not on a machine right now but something like
`nix-store -q --requisites` will give you everything that depends on a
packages. I always get the actual wording confused but the man page has
excellent descriptions in the query section.
Hope that helps, Kevin
