Thanks for the hint. I think I found something:

hilti at kirk:~/dhcpd> script log  sh -x /usr/sbin/service -e
[snip]
+ grep -q ^rcvar /etc/rc.d/yppasswdd
+ grep ^name= /etc/rc.d/yppasswdd
+ eval name="yppasswdd"
+ name=yppasswdd
+ grep ^rcvar /etc/rc.d/yppasswdd
+ eval rcvar="nis_yppasswdd_enable"
+ rcvar=nis_yppasswdd_enable
+ checkyesno nis_yppasswdd_enable
+ grep -q ^rcvar /usr/local/etc/rc.d/isc-dhcpd
+ grep ^name= /usr/local/etc/rc.d/isc-dhcpd
+ eval name=dhcpd
+ name=dhcpd
+ grep ^rcvar /usr/local/etc/rc.d/isc-dhcpd
+ eval rcvar_chuser () rcvar_jail () rcvar_chroot () rcvar_pidnleases ()
rcvar_rooted () rcvar=${name}_enable
+ checkyesno nis_yppasswdd_enable

Seems 'grep ^rcvar /usr/local/etc/rc.d/isc-dhcpd' finds more than
expected. I added a '=' in /usr/sbin/service and changed the line to
eval `grep ^rcvar= $file`. Now it works like expected.

But there is stil one question. Why it works in 7.4-RELEASE with newer
dhcpd? 
| hilti at kirk:~/dhcpd> grep ^rcvar isc-dhcpd_*

| isc-dhcpd_3.1.in:rcvar_jail ()

In both files more than one result. And there was no change in
service(8) between 7.3 and 74. Strange...
