[ Noticed doshutdownhooks() is not called on most ports... ]

Yes, all ports should probably call this.  Perhaps the creation of
this function was not announced loudly enough to the port masters...

Yes and no.  It allows you to either reboot or halt, possibly with
a crash dump, and on some ports you may specify reboot parameters.
(i.e. the Sun PROM lets you specify the device/kernel for reboot.)

Most of the machine-independent code is now gone from boot() on
the ports I've looked at (reboot_sync stuff is common now).
The remaining code IS possibly machine-specific, and there are
only about sixty lines of it left.  I think it's good as-is.
(Other than the need to call doshutdownhooks or whatever.)
