Can you elaborate on this a bit more as well. What you are actually doing
in the
patch is adding to the RDEPENDS of openvswitch and it's the dependencies
that
you are adding, that once installed are starting the switch at runtime ..
right ? The
reason I'd like it clarified is that when I read your patch, I expected to
see an initscript
update, or inherit rc.d, but found the RDEPENDS update instead.

This looks fine. I double checked that the vswitch kernel fragment enables
the module,
so our autoload is fine.
