From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

does anyone know what effect these warnings have when installing or running a nix package?

warning: Ignoring setting 'auto-allocate-uids' because experimental feature 'auto-allocate-uids' is not enabled
warning: Ignoring setting 'impure-env' because experimental feature 'configurable-impure-env' is not enabled

I'm using Nix on Fedora.

It’s exactly what it says. Your nix config has a setting that has no effect without enabling the experimental feature that uses it. Either enable the feature, or remove the setting

You don't have the features "auto-allocate-uids" and "configurable-impure-env" enabled, so "auto-allocate-uids" and "impure-env" options are ignored in your config.

Check your nix.conf.
