Tiny Tiny RSS init-script for multiple instances on Debian Wheezy

Mon, 09 Feb 2015 04:04:51 +0000

Well, I have a bunch of Tiny Tiny RSS instances running on my webhost, and I wanted a init-script that starts the update-daemons for all instances.

Now, there’s already a bunch of init scripts for Debian around ( 1, 2) however none of them were to my liking or did what I wanted it to do. So I ended up (yeah, I know again) rewriting them.
