nixpkgs/pkgs/development/libraries/consolekit/commands.patch

This patch adds shutdown commands specific to NixOS, as NixOS does not have
a /sbin or /usr/sbin directory. In order not to have a dependency on the
package that provides "shutdown" when in an environment other than NixOS,
we'll make it depend on /var/run/current-system.

Note: this patch does not compromise system security. Other systems than
NixOS should have already shutdown in the earlier directories being searched,
and otherwise /var/run is writable only be root.
