Containers can be considered the third wave in service provision after physical boxes (the first wave) and virtual machines (the second wave). Instead of working with complete servers (hardware or...

Infinite BusyBox with systemd

Lightweight virtual containers with PID 1.

In this article, I demonstrate a method to build one Linux system within another using the latest utilities within the systemd suite of management tools.

On April 23, 2015, Ubuntu version 15.04 (code-named Vivid Vervet) was released. This is an important release, although superficially it looks much the same as the previous version. The real difference is "under the skin", as Ubuntu switches from the Upstart init system to systemd. more>>
