Maybe it is a good idea to provide the samba tool-set by default. You could
add the following to your samba-service-type:

(service-extension profile-service-type
                   (compose list samba-configuration-samba))

Some of the samba tools are broken though. I send a patch some time ago
which tries to address this issue. Maybe you want to take a look?
