Ops, meant to submit a new one...

Why eerror produces no output?

In grml-debootstrap.clp

if [ $? != 0 ]; then
  eerror "Try `grml-debootstrap --help' for more information."; eend 1; exit 1
fi

but I never get this message.

maybe 

-d, --confdir 

is better.

Hi mika, 

Please check out my newly committed patches to close Issue546 first.

Now, I propose a new command line parameter for the CONFFILES var.

How about
 --configs=dir  place of config files for debootstrap, defaults to
/etc/debootstrap/ 

or --confdir, or...?

thanks
