# This creates some list of packages so that we could rebuild her machine
# if needed.  In theory her system could be restored by the
# following steps:
# 1. Install Debian on another disk
# 2. run "cat /etc/dpkg--get-selection | dpkg --set-selections" to sync
# the list of packages.
# 3. Install all the packages "apt-get update ; apt-get dselect-upgrade"
# 4. Use tar or whatever to copy /etc. ie get all the settings.
# 5. Recover other directories mentioned below, ie /home.
