As an addition, you can copy your launcher to:

'<used-file-system>/config/<Sculpt-Version>/launcher/' , for example,

!  cp /config/launcher/test /rw/config/22.04/launcher/

when using the system shell.

This way the launchers will be restored to '/config/launcher' upon next usage of 
the file-system (in case it is persistent). The same goes for the 'deploy' file. 
In case you want to restore your whole setup upon next usage copy:

/config/managed/deploy to /rw/config/22.04/deploy

Note that you have to update these files with each Sculpt release because the 
packet versions will change.

Regards,

Sebastian
