Hi Vasek,

I've just noticed that POWERDOWNFLAG defaults to

on /run: not all the world is Linux (sadly) ;)
on /tmp, /var and the like: by the time this killpower flag file is useful,
at the very end of the system shutdown process, these dirs may have been
wiped out. Refer to
http://www.networkupstools.org/docs/user-manual.chunked/ar01s06.html#Shutdown_design

so, /etc, or {sysconfdir} to be right (I've just fixed it in commit r3793),
is still the best default.
note that r3793 was another long standing commit underway...
that said, everyone is free to set this to whatever values that better fits
particular needs.

managing from legacy Unix and Windows to the bleeding edge Linux implies
some compromise...

cheers,
Arnaud
