units: add systemd-debug-shell.service If enabled, the service provides a root shell from an early boot. It also remains active late into shutdown. It is useful for debugging startup and shutdown problems. This is the unit referenced in http://freedesktop.org/wiki/Software/systemd/Debugging#early_debug_shell 2012-06-07 18:03:33 +04:00			`[Unit]`
meson: use jinja2 for unit templates We don't need two (and half) templating systems anymore, yay! I'm keeping the changes minimal, to make the diff manageable. Some enhancements due to a better templating system might be possible in the future.
