   In the next screen you should tell debconf to be quiet, setting

   will be configured using default values, it's ok, since they
   will be reconfigured by 'kusa' on the run.

   Remember, if you need to restore the default (interactive)

KUSA-BOOTSTRAP POST INSTALL TASKS
------------------------------------------------------------------------------

1. edit /etc/kusa/kusa.conf to accomodate your needs; check kusa.debug too

2. as first run, launch   kusa-reconf -b  to install default kusa-db entries

3. configure first, basic, modules: net and repositories

   kusa net base-repos

4. standardize the userbase and reboot the machine:

   kusa -s base-users base-users

5. configure the remaining modules
