But /etc/named.conf has always been the dependency, I mean before smf(5):
# cat -n /etc/init.d/inetsvc | head -81 | tail -10
72 #
73 # If this machine is configured to be an Internet Domain Name
System (DNS)
74 # server, run the name daemon. Start named prior to: route add
net host,
75 # to avoid dns gethostbyname timout delay for nameserver during
boot.
76 #
77 if [ -f /usr/sbin/in.named -a -f /etc/named.conf ]; then
78 echo 'starting internet domain name server.'
79 /usr/sbin/in.named &
80 fi
81
Surely it makes sense to keep this dependency.
Further more use the dependency FMRI as the
location that named should use for the configuration file:
/*
* Within the SMF framework the default location of the
* configuration file is held within the application instance
* property in the form of an FMRI. If unable to detect a
* valid configuration file then exit. Note that this
* condition should not occur as the service should not have
* been started if the property or file did not exist!
*/

Which is the bug that my code above would address.

Both possibilities exist, their is a requirement to run one service
multiple times.

That would help. It is possible that one would simply want to duplicate
everything as-is except for one parameter.
