Oh!  That's documented in acpid.  You create ONE event rule in each file. That's
just "the way it works" (TM).  You can, however, create multiple rule files for
the same event (ie, if you keep the event=.* rule in one file, and the lid rule
in another, both will be executed - but there's no guarantee in which order!)

Er, those aren't at all the same function.  swsusp is either S3 (suspend-to-ram
only under 2.5/2.6 kernels) or S4 (suspend-to-disk).  Your 'gotosleep' is S1
which is just (supposedly) an idle state.  So you shouldn't get the same
results.

There can't possibly be a recovery.  Whether you really went to S1, or didn't
change sleep states at all, if the machine powered off, it's OFF, not suspended
:-(

What happens when you execute either gotosleep or "echo 1 > /proc/acpi/sleep"
without closing the lid - do you get the expected behaviour?  This is why I have
asked at least twice how your script knows you closed the lid rather than opened
it?  It looks to me like when you close the lid, it goes to S1, then when you
open the lid...it goes to S1.  But I'd really expect to be able to wake it from
there.
