Thanks for your suggestion, but unfortunately that doesn't work in my
scenario.

I have a oneshot that needs to perform, let's say, more complex
operations than I'm willing to implement with execline ATM. So I want to
call a regular shell script from the up/down files.

However, since oneshots ignore the shebang I can neither change the
interpreter, nor pass arguments to execlineb. And the working directory
is that of the oneshot runner, so I also can't invoke the shell script
with a relative path.

It's no biggie, though. I just wanted to confirm that I need to call the
script with absolute path.
