Creating service directories and files

runit is a reimplementation of the daemontools process supervision kit. It was created by Gerrit Pape as a replacement for System V init and other Unix init schemes. At the time of writing, the two best sources of information on runit were Pape's website (http://smarden.org/runit/) and Void Linux's online documentation.

BusyBox's implementation of runit differs from standard runit mostly in terms of
self-documentation. For example, sv --help makes no mention of the sv utility's start and check options, which are in fact supported by BusyBox's implementation. The source code for BusyBox runit can be found in BusyBox's output/build/busybox-1.31.1/runit directory. You can also browse the latest version of the BusyBox runit source code online at https://git.busybox.net/busybox/tree/runit. If there are any bugs in, or features missing from, BusyBox's implementation of runit, you can fix or add them by patching...
