I tried it , before bind is installed, and before munin is installed,
and it worked with almost no delay.
After bind is installed and started, during the initialization of the
munin-plugins it takes almost 16 seconds.
If I stop bind, it only takes 0.165 seconds.
After the installation completed the function takes 0.216sec
But so yes, there is a problem with bind if we have not set up our
envrionment before bind is installed. BUt that still doesn't explain
why there is some traces of looking up "tjener.intern.intern." and
"tjener.intern.intern.intern." during initialization of munin-plugins
