Title:
Powernap should ensure WoL is enabled before Second Stage
Status in powernap:
Confirmed
Status in pm-utils package in Ubuntu:

Status in powernap package in Ubuntu:

Bug description:
PowerNap should ensure that WoL is enabled before executing the second
stage action (poweroff/susped) as first stage action (powersave) will
disable WoL.
Note that powernap does not disable WoL, but rather, pm-utils ships a
script called disable_wol.
============= Background ================
I have a server running Ubuntu 12.04. The current issue is the following:
* if I activate 2nd-stage powernap to poweroff (or 'shutdown -h' by
using /etc/powernap/action), the computer will not wake when sent a
magic packet.
* if however, I manually shutdown the computer (using shutdown -h from
the console), the computer can be woken up with a magic packet without
any problem.
I have no idea about the reason for this. I used previously powernap
with 11.04 (or 11.10, I don't remember) and it worked correctly (the
current installation is a clean one).
I have attached the powernap main config (with 2nd stage deactivated,
but of course I ran the tests by activating it).
Note that the symptoms are the same if I try using suspend instead of
poweroff/shutdown -h
