Infra02
=======

Purpose
=======

The infrastructure host system Infra02 is a dedicated machine for the CAcert
infrastructure.

Infra02 is the host system for all infrastructure containers. The containers
are setup using the Linux kernel's LXC_ system. The firewall for infrastructure
is maintained on this machine using Ferm_.

.. _LXC: https://linuxcontainers.org/
