Hmm yes - I guess its not as clean cut as I thought, but I would still
argue that this patch is the lest surprising alternative.

One tweak I am thinking of working on soon is a "pause-on-reboot"
feature which is a bit like noreboot, but will accept a passphrase and
continue with the reboot, so you can 'pause', see the dying panic then
reboot without needing to invoke the server power management.

(This may have been as a result of being given details for the wrong
server power management interface IP address when debugging a server in
a data center 7 time zones away, and getting rather confused when it
didn't make any attempt to reboot.  I imagine someone else might get
equally irate if their server was rebooting without warning.)
