Well, at least shutting down the machine when the power button has
been used to wake it up doesn't make sense at all for a default
configuration, thus should be regarded as a bug.
BTW, I can see in /usr/share/doc/acpid/examples/powerbtn.sh that it
does:
# Skip if we just in the middle of resuming.
test -f /var/lock/acpisleep && exit 0
I suppose that this handles the problem I've mentioned.

But the lack of a namespace means that acpi-support can conflict
with what the user does. For instance, the acpid(8) man page gives
an example:
------------------------------------------------------------
EXAMPLE
This example will shut down your system if you press the power
button.
Create a file named /etc/acpi/events/power that contains the
following:
event=button/power
action=/etc/acpi/power.sh "%e"
Then create a file named /etc/acpi/power.sh that contains the
following:
/sbin/shutdown -h now "Power button pressed"
------------------------------------------------------------
but acpi-support uses the file /etc/acpi/power.sh chosen in this example
for something completely different. If the user creates this file
following the example before installing acpi-support, bad things will
happen when acpi-support is installed (since overriding a user file is
not acceptable, this user file will be used by /etc/acpi/events/battery
and /etc/acpi/events/ac for something that it is not expected to do).
Similar problems could occur with upgrades, when new config files from
acpi-support need to be installed.
