Benjamin Franzke 2eca6d602f docs: overhaul styling for example log messages on startpage
* Use brand-green for demo log messages on the startpage
   instead of the default `green` color defined by the browser vendor
   (after all, the brand green color is intended to reflect the
   boot status output)
 * Add a matching blue intro color (mixed using HSL from brand-green
   by 55deg hue rotation and 4% lightness)
 * Use a defined font-size
   (to avoid blurry rendering at 13.33333px, due to font-size: smaller)
 * Add possibility for the browser to show horizontal scrollbar
   (avoid overflow in mobile view)

System and Service Manager

systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system.

systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit.

Other parts include a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.
