Service start up scripts are not part of the dhcp distribution, so
there's no clear answer to this one. However, a couple of general
svcadm troubleshooting tips are to use
svcs -xv isc-dhcp
then examine the svc log file given in the output from that command to
see what error dhcpd is reporting.
Then you need to see why svcadm is putting the dhcp service into
maintenance mode when that error occurs. It might mean a change to the
service manifest to allow for that error, or to the service startup
(For the rest of the list members, this svcadm is a new feature in
Solaris 10 and Opensolaris. It controls the startup and shutdown of
services, a bit like the old init.d scripts, but on steroids!)
