Review Comment:
   @anmolnar I'm not sure adding shellcheck is helpful here. The `libexec` 
folder does not exist at this point so we can not verify if it has the file. I 
could add `# shellcheck source=/dev/null` but that basically circumvents the 
shellcheck and at that point I would prefer not to touch the script at all.
