Bernhard,

This change wasn't well-tested and has broken the runqemu script for 
both bash and dash. :(

 From what I can tell, the =~ regex operator is a bashism. It's also one 
that helps a lot with the code readability. So now that we're faced with 
re-writing the script to avoid using that operator, I'm having second 
thoughts about whether the runqemu script really needs to be 
shell-agnostic. The alternative of invoking grep or other commands to 
process the name patterns does not appeal to me.

I can understand why we're trying to ensure our build system doesn't 
require /bin/sh to be bash, but I think support scripts like runqemu 
might be a special case.

What do other people in the community think of this? The runqemu script 
isn't trivial, and it has to run in a lot of different contexts. Should 
we put the time in to make it shell-agnostic, or allow it to require bash?
