Hi,

can you please explain how Ubuntu reads and stores the hwclock? What happens when and in which order during startup and shutdown? How are the scripts triggered?

I'm working on a script that will set the acpi wakeup timer for a digital video recorder (based on vdr).

This acpi setting is lost when hwclock is called. Therefore it is necessairy to set the acpi wakeup timer _after_ the system clock is stored in the RTC during shutdown.

So where do I put this script so that it will always be called after hwclock?

Thank you in advance to anyone taking the time explaining this!

Regards,

Hanno
