vpsAdminOS can be built from its repository using
make, which is calling
nix-build under the hood. Check the Makefile for more information. Another
approach is to use
os-rebuild, an alternative to
an already installed system.
At vpsFree.cz, we use our own tool for deploying vpsAdminOS and NixOS called confctl.
vpsfree-cz-configuration is a confctl configuration used at vpsFree.cz. It also contains modules to build a PXE server to boot vpsAdminOS systems over network.
The main difference between building NixOS and vpsAdminOS is that when building
NixOS, you import module
<nixpkgs/nixos/lib/eval-config.nix>. To build
vpsAdminOS, you need to import
<vpsadminos/os/default.nix>. Examples of the
necessary changes can be found at our deprecated forks that include vpsAdminOS
