Don't mix it with the user interface or "halt", it is completely
I would go for (2), since there already is "gracefull shutdown" code
but it needs MD extensions for this case.
I am rather interested in a way to fix power management limitations
found for the "sleep" case, where it is silently "ignored" (well, you
only get a system message indicating that sleep button was pressed) when
powerd(8) is not running. This is already done for shutdown and reboot.
The "sleep" case is missing. We have to choose between error reporting,
or add a hook to sysmon wrapper so we can call MD suspend code.
Regarding user interface, although it's somewhat related to my issue,
it's secondary: I can always hack around the MD stuff, and fix the
interface later when we'll have a sane API (like the one Jukka mentions
IMHO, the RB_SLEEP flag for cpu_reboot(9) is the more logical, as
shutdown, reboot or sleep events share things (at least from a system
perspective). Although current MD cpu_reboot(9) for x86 does not look
that much flexible :)
