Disaster recovery

[Rich Johnson <rjohnson@dogstar-interactive.com>]

Hi folks--

Let's see:  To recover from a destroyed machine (fire, flood, 
head-crash) I need:
 - debian install disk/CD for the new machine (which may be a different 
architecture).
 - list of installed packages (dpkg --get-selections)
 - backup of non-standard .conf files
 - server data backup  (account info, db's, etc.)
 - user data backup.


Is there a way to list the _non-default_, or modified, .conf files 
required to transferd/or restore a configuration?
Files like:
- krb5.conf;
- httpd.conf
- timezone
- cron.d files
- bind files

I already maintain the list of packages (dpkg --get-selections) but that 
  only yields a default configuration.

Thanks,
--rich
