Maybe I am only too stupid to find out how it actually works, but I'd like to have a script that will be executed while shutdown, which is not overwritten by Systemupdates.
This could be used to send Commands to external components like home automation, receivers, e.g.
The other way (sending commands during startup) would also be nice, but is at least for me not that important since my HTPC is not reestablishing HDMI after failed Hardware-Test ( for the Receiver to provide a virtual monitor)
The change should not be too big (e.g. a link to specific file in the Samba accessible Share)
What do you think - could this be possible ?!?
