Nope, everything but. Just like the Google entries. But this is
new stuff, so it's gonna be that way. And it's complicated, too; making
just one selection opens a roadmap to a whole host of detailed options,
too, and to make it worse, it's somewhat up in the air.
This isn't the first event in a series of changes that make FC2
more-beta than previous versions....except maybe 4.x->5.x with all the
library changes. But that was simple compared to this.
Do you have any idea what command lines I'd use to chose a scheduler
option? I've seen sched.c, and a flock of scheduler programs....I just
don't really know how to chose'em.
elevator=as? I'd like to try the AS first, then PB...
