I think it would make sense to emit a warning when `--user` is used as UID 0, so you'd end up with the following situation: * `pip3 install --user <install-args>` remains unchanged * `pip3 install <install-args>` usually just works (since we have `~/.local/bin` on the default PATH) * `pip3 install --global <install-args>` handles RPM and container builds * `sudo pip3 install <install-args>` stops even appearing to work for user-run scripts (since it installs into /root), no longer conflicts with DNF, and emits a warning * `sudo pip3 install --global <install-args>` is available if you really know what you're doing and are prepared to deal with the consequences If the main goal is to protect naive users from inadvertently breaking their system Python, making `sudo pip3 install <install-args>` do something sensible doesn't seem valuable enough to me to maintain an upstream/downstream behavioural discrepancy over the long term. However, there's a *different* question, which is whether or not we want `sudo pip3 install --global <install-args>` to be a nominally supported thing to do, rather than a matter of "You're a DIY system integrator now, welcome to the club!". If we genuinely want to do that, then yes, we'd need something more like the Debian --install-layout patch. However, one of the problems with that is that it currently targets setuptools/distutils specifically, which may be a problem as the upstream changes to enable more flexibility in the build pipeline come into effect.
