yeah currently do a rdiff-backup / backupserver::/system so I get every
thing, but I am guessing saving package listing and package conf - not
etc stuff - but the stuff that you are asked when installing a package
(debconf I think) would be good to backup.

Even though I have every thing backed  up, I would still like to
re-install and reconfig as needed
