Try to use GitHub actions to automate testing

At least once a week, but there is a need for auto report of logs and what is success and failure

There is a setupdonehalt option which halts instead of restarting machine when cd is done.
Could we introduce a "halt after first boot" - which adds a local.d/shutdown.start script, that script halts the machine and removes itself. - be carefull of order - but (rm $0; halt) & hoepfully works.
