 ====== vpsAdminOS ======
-Since OpenVZ Legacy is no longer supported and new distributions
+vpsAdminOS is a host system for containers developed by vpsFree.cz. We use it
-don't work there, we had to find a way to upgrade our kernel, which
+to run our VPS.
-meant choosing a different virtualization technology. Linux kernel now
-has some support for containers, so we've decided to use it.
-We needed some distribution that we could use on nodes to serve as
-a hypervisor, as a replacement of Scientific Linux 6 with OpenVZ kernel.
-We've chosen [[https://nixos.org|NixOS]], because it allows us to declaratively
-configure the system and its services. And since our requirements are quite specific,
-we're maintaining our own spin of NixOS called vpsAdminOS.

-vpsAdminOS naturally integrates with vpsAdmin, our administration interface
+of vpsFree.cz's infrastructure, e.g. on your home server.
-with web interface. However, vpsAdminOS is meant to be fully usable even on its own,
