Great!

Sure, I'll adopt it for zsh and integrate the colorful output. :)

Just use the bootoption 'nodhcp' to disable startup of pump.

I'm even thinking about integrating your code into grml-autoconfig,
so you can use it with a new bootoption on every grml version.
I've to take a closer look at the code, but I'll ping you via #grml
anyway. ;)

Thanks, Marc!
