nixos-checkout: Remove

Browse Source 
This command was useful when NixOS was spread across multiple
repositories, but now it's pretty pointless (and obfuscates what
happens, i.e. "git clone git://github.com/NixOS/nixpkgs.git").

To modify NixOS, however, you should check out the latest sources from
Git. This is done using the following command:
Git. This is as follows:
<screen>
$ nixos-checkout <replaceable>/my/sources</replaceable>
</screen>
or
<screen>
$ mkdir -p <replaceable>/my/sources</replaceable>
$ cd <replaceable>/my/sources</replaceable>
$ nix-env -i git
$ git clone git://github.com/NixOS/nixpkgs.git
$ cd nixpkgs
$ git remote add channels git://github.com/NixOS/nixpkgs-channels.git
$ git remote update channels
</screen>
This will check out the latest NixOS sources to
<filename><replaceable>/my/sources</replaceable>/nixpkgs/nixos</filename>
and the Nixpkgs sources to
<filename><replaceable>/my/sources</replaceable>/nixpkgs</filename>.

read-only repository that tracks the Nixpkgs/NixOS channels (see <xref
