• Setting locale, timezone and reconfiguring packages non-interactively on Debian and Ubuntu

  localectl, timedatectl and update-locale change locale and timezone without a text-mode dialog, and dpkg-reconfigure -f noninteractive re-runs a package's debconf-driven setup the same way a script would run the original install, both usable in provisioning scripts with no terminal attached.
