A word was missing
  • I've got a Raspberry Pi running Raspbian, which I'd like to reinstall from scratch. However over time I've made *many* changes to the configuration (installed new packages, changed the name of the default user, created a new user account, and probably a lot of things I tweaked but forgot about), and unfortunately I usually didn't think of documenting those changes.
  • What would be the best strategy to figure out as many of those changes as possible before reinstallation, so I don't have to figure out them afterwards through things no longer working the way I want them?
  • In particular, I'd be interested in the following things.
  • * How does the list of packages differ from that in a fresh install?
  • * Are there any changes to configuration files that were not done by package installation/update, and to which files?
  • Methods that work also on other Debian-based are preferred.

Fixed a typo
