Installing Nix without root is possible by using nix-user-chroot, which creates a user-space chroot and maps a writable directory to /nix. This allows Nix to work in environments where you cannot create or write to the real /nix path.
Reference:
Working on a system without root privilege is challenging when you need to install utilities. Homebrew is a popular rootless package manager widely used on macOS and Linux. However, installing Homebrew typically requires temporary root access to write to /home/linuxbrew.
While you can install to any other writable directory, this approach is unsupported and prevents access to pre-built binaries ("bottles")—meaning almost everything must be compiled from source, which is slow and tedious. This guide provides a workaround using PRoot to "fake" a writable /home/linuxbrew directory for your user, allowing Homebrew to function seamlessly without root access.
