This script is bad and should not be used. I suspect it's just slightly modified copy pasta from somewhere else, but the end result is nonsensical and mostly works by blind luck. There are valid alternatives in https://github.com/syncthing/syncthing/tree/master/etc and in the release / Debian packages.

@Morrisman68 of course you need to :))
sudo update-rc.d syncthing defaults

@calmh Sorry, I cannot find a sysvinit script in either of those places. I find runit, upstart, systemd among others, but no sysvinit script.

A better sysvinit script was submitted in this Syncthing issue: Debian SysVinit Script #2990. The Gist of it can be found here.
