Fossil once attached to venti can't serve = without it, so venti must arrive first.
My machine is fossil+venti= , so not quite what you asked about, but the mechanism would

The kernel uses configuration pcfs, = which contains enough in bootdir to start and run fossil,
which c= hecks $venti (set in plan9.ini) to see if it should run that first, if loca= l. If venti isn't
local, it sets up the network so foss= il can dial it.
/sys/src/9/boot/local.c organises that= . I don't think a configuration is provided
that starts = just venti, but some of the pc* configurations in /sys/src/9/pc hint at way= s to
make various custom systems.

I am curios.
In an environment where you have separate machines for fossil and venti, do you boot fossil first, and let venti pxe boot over it,
or do you boot venti first, with a small, local, fossil partition?
