  | Hi Robert,
  |
  | please allow me one mor more question....

Sure, but this one I cannot answer, I know nothing about the
module build system, so I am punting this to Paul Goyette,
the expert on all things module related.

Paul?

  |
  | ```
  | $ cd /build/netbsd-93-1000hz/usr/src/sys/arch/amd64/conf
  | $ cp GENERIC VHOST
  | $ vi VHOST
  |
  |      options		HZ=1000
  |
  | $ cd /build/netbsd-93-1000hz/usr/src/
  | $ mkdir ../obj
  | $ ./build.sh -O ../obj -j 4 -U tools
  | $ ./build.sh -O ../obj -j 4 -U kernel=VHOST
  | $ ./build.sh -O ../obj -U releasekernel=VHOST
  | ```
  |
  | ...and picked it up from
  |
  | While for the *kernel* / *releasekernel* target the name of the kernel
  | configuration to be used can be provided, I don't see such an option for
  |
  | the *modules* target. How can I make sure the modules are built with the
  |
  | HZ option set in VHOST config? Or does it simply adapt these from a
  | previous run of the *kernel* target?
  |
  | Kind regards
  | Matthias
