From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You can end up with a lot of boiler plate code and with duplication you run the risk that one unit tweaks the boiler plate in a way that behaves differently. This isn't insurmountable and a lot of rc scripts source a library of common functions shared between units. However from the point of view of the executor each unit is it's own whole ball of shell script code.
Most service scripts on my machine (Void with runit) are less than 10 lines long, and don't contain any "boiler plate" other than a shebang.
