Yes of course... but I didn't want to specify the mac-address twice.
More comfortable would be to add a option to  the already existing
groups of hosts:

group { # guests
    option tfd-scope-identifier "gaeste";
    host test1 {
       hardware ethernet aa:bb:cc:dd:ee:ff;
    }
    host test2 {
       hardware ethernet bb:cc:dd:ee:ff:aa;
    }
}

this way I would have to add the MAC-address twice (one time for the
subclass and one time for the host)

The pool-declarations are in a shared-network, but even changing this,
so that the pool-declaration are in the corresponding
subnet-declarations, doesn't help.

It seems to me, that class matches doesn't work with config-options,
only with options :(
I tried once to use "option host-name " instead of my "config-option
tfd-scope-identifier" and then the class was assigned.

Thanks so far
