Distutils2/packaging does not support all the flags provided in distutils (e.g., --user, --prefix, etc.). It would be good to provide the same level of install control (or at least support the --user flag).

[merwok]

To be clear, the distutils2 install command (currently spelled install_dist but see bpo-13160) does have all these options, it’s the install action that needs to expose them too.

[merwok]

The command line parsers need a thorough cleanup before this can be implemented. Ideally with a new, clean system the install action would just pass all its options to the install command and let it do option validation.
