The GNU Shepherd Manual (gnu.org)
This manual documents the GNU Daemon Shepherd, or GNU Shepherd for short. The Shepherd looks after system services, typically daemons. It is used to start and stop them in a reliable fashion. For instance, it will dynamically determine and start any other services that our desired service depends upon.
Using /tmp/ and /var/tmp/ Safely (systemd.io)
/tmp/ and /var/tmp/ are two world-writable directories Linux systems provide for temporary files.
Traditionally, init on Unix was not a service manager as such (utoronto.ca)
Init (the process) has historically had a number of roles but, perhaps surprisingly, being a 'service manager' (or a 'daemon manager') was not one of them in traditional init systems.
A word about systemd (2016) (skarnet.org)
systemd is becoming de facto a standard init system for Linux. But even this choice of words is treacherous, because systemd is much more than an init system. It's basically an integrated redesign of all the low-level userspace of a Linux system, with great plans to change how software is run and organized.
S6 – Skarnet's small supervision suite (skarnet.org)
s6 is a small suite of programs for UNIX, designed to allow process supervision (a.k.a service supervision), in the line of daemontools and runit, as well as various operations on processes and daemons.
