Best way to backup all settings, list of installed packages, tweaks, etc?
I've heard that I can dump the dpkg package list of currently installed applications, then after I re-install, re-import that list and have apt or dpkg do all the heavy lifting for me getting my apps re-installed.
How do i do this?
To dump the list of currently installed applications:
dpkg --get-selections >output-file
To re-import:
sudo dpkg --set-selections <output-file
sudo apt-get dselect-upgrade
