As a sysadmin you can do anything you want and are free to deal with the breakage you cause yourself. But the FHS pretty clearly establishes what behavior an application such as Nix should have: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03.html#purpose2 https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03.html#p... Quote: "Applications must never create or require special files or subdirectories in the root directory. Other locations in the FHS hierarchy provide more than enough flexibility for any package." They can choose not to abide the FHS, and that's fine if the users are happy with that tradeoff. But OSes observing the FHS are free to break Nix's expectations because they don't align with the FHS.
