I'm fine with using .config as first choice (that is what the script 
originally did) but I wanted to make it as easy for non developers as 
possible. Taking from /proc or /boot was most likely the best to give a 
minimal boot environment.

But I can see why .config is probably the best choice for having the most 
power with the tool. It is how you can always force it to do something you 
want, and is the most logical place to expect the script to read from.

I'll update it.

Thanks,
