I did build the kernel with build.sh as follows:

```
$ 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
	 
/build/netbsd-93-1000hz/usr/src/obj/releasedir/amd64/binary/kernel/netbsd-VHOST.gz
for deployment on the actual vhost.

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
