You can currently only change at boot time. There aren't any plans to allow
runtime changes - sysadmins will probably just statically configure the
scheduler that they prefer for their setup.

There's no examples t the moment but there's some more detail on Atropos in
the user manual and the Sched-HOWTO.

That looks right. The Atropos port is probably broken at the moment as it's
in the process of being updated to the latest scheduler interface.
