The is_windows() check isn't broad enough; macOS hosts also do not use udev and will raise an exception at this step.
I'd personally remove the exception for the general CustomInstall. Even on Linux hosts, if one is installing in a virtualenv with this as a module inside another project's requirements, it's not good to have to run all project dependencies as an elevated user. It would be better to mention in the README regarding udev rules.
