sys-apps/apcupsd should also install the file examples/safe.apccontrol into /etc/apcupsd/, which it doesn't do now. This file can be used to prevent apcupsd from really shutting down the maching as explained at http://www.apcupsd.com/manual/testing.html (see section "Simulated Power Fail Test").
how about provide us a patch ? ;)
fixed in -r3
