Please allow me introduce power management cases on Solaris. Currently,
Solaris has its own PM framework, which consists of a system daemon and
some configuration GUI. But they're very old and less flexible than HAL
& G-P-M. Without system daemon, G-P-M can't replace current PM framework
entirely. Now I'm thinking how to put them into together on Solaris.

To be honest, I'm new to GonsoleKit. How does it run g-p-m instance if
no session on machine, e.g. when system just starts?

Sorry, I'm not sure. In fact, Solaris lags behind many other OSs in this
aspect. AFAIK, some colleagues are working on virtual console project. I
think ConsoleKit or similar tool is necessary for them.

In addition, I notice Solaris PM framework can switch off hard drive
when idleness. Windows also supplies the simaliar feature. Will G-P-M
support it later?
