When you write bash script to serve as startup script for systemd, dont forget #!/bin/sh at 1. line of script
Debugging why systemd won't execute it is frustrating experience 😩

@entangled You didn't test it as an independent script before trusting it? Strike your own fingers with a ruler. ;)

@AskChip I wrote the script, it's simple, 4 lines. It works perfectly fine without #!/bin/sh when started manually, but systemd won't execute it.

@entangled Strange, thought I had them not run back when i forgot that line.

@AskChip Thing is, systemd doesn't consider bash as default interpreter for script files, which makes sense, but in a concrete situation is a pain to debug

@entangled "…systemd…is [a] frustrating experience…" :-P
