Systemd scripts to run once upon next boot

run sudo setup.sh which will:

• create a user writable directory at /etc/local/runonce.d
• install an executable script runonce.sh in /etc/local/bin/
• create and enable a systemd service installed at /etc/systemd/system/runonce.service
• install a helper reboot-defer command in /usr/local/bin

Defer a script to run after next startup with the reboot-defer command

reboot-defer foo.sh

You can also add a deferred script by placing it in /etc/local/runonce.d/

cp test.sh /etc/local/runonce.d
