[arch-general] APM gets re-enabled after awake from suspend

my hard drive suffers from the "clicking" problem, therefore I
deactivated the APM (Advanced Power Management) totally.

I'm doing this using hdparm in the /etc/rc.local, making sure that it
gets executed every time I boot up my machine.

However I noticed that the APM gets re-enabled after I wake my machine
up from Suspend-to-RAM, which makes the hard drive clicking again.

I'm now wondering whether this is "normal"? I guess so, as the hard
drive gets disabled during the suspend, and after a wake-up it gets
re-enabled, so any changed made with hdparm don't get stored. Is this
intention right?

Secondly I want to know what would be the right file (place) to fix
this. I'll have to execute the hdparm command again, but don't quite
know where to put it, or at least where it should be put ;).

Best regards,
