In this episode, Martin and Chris discuss init systems and Chris outs himself as a systemd fan boy (Devuan followers take note :-). Even Linux and other FLOSS OS geeks not interested in what happens when you flick the power switch on a computer may find this episode (vaguely) interesting as some light is also shed on the philosophy of the different system architectures and their history (Ever wanted to know what an /360 IPL really is? Then stay tuned...). Disclosure: The following text may resort to regular expressions to keep things concise and simple. Some of the PCRE-challenged readers may take offence - you have been warned.
