I think there's some misunderstanding here. All power control events
use the same xenstore node (~/control/shutdown), but the command read
from it is different depending on the requested action (poweroff,
reboot, halt...).

See [0] for a slightly more detailed description of the xenstore node.

Note that this commit doesn't change any of this logic, it just clears
the contents of ~/control/shutdown (by writing "") so the toolstack
knows FreeBSD has acknowledged the request and it's processing it.

Roger.
