## The purpose of the wrapper is to install the closure of the actual
## installer.  It needs to work on pure NixOS as well as hybrid
## systems using an arbitrary Linux distribution with nixpkgs
## installed.  It is assumed that /bin/sh exists everywhere and
## provides a basic bourne-type shell.  The id, tail and xz utilities
## are also assumed to be in PATH.  The nix-* commands are located in
## /run/current-system/sw/bin/ on NixOS and in
## /nix/var/nix/profiles/default/bin on hybrid systems.
