"fast" reboot without BIOS involved?

Hi folks,

would it be possible to add some kind of "fast reboot" to OpenBSD?

* shutdown all userspace
* run boot, using the old kernel to load a new one
* start init again

The "traditional" reboot gives me a downtime of 2 to 3 minutes on
some hosts, before the boot prompt is shown. I would like to avoid
that, esp. after a syspatch.


Regards

Harri
