I have, in my svscan.sh,
# PROVIDE: svscan
# REQUIRE: SERVERS cleanvar
and I also have a /usr/local/etc/rc.d/dnscache which looks like
#!/bin/sh
# PROVIDE: named
# REQUIRE: svscan
. /etc/rc.subr
. /usr/local/etc/svc.subr
name="dnscache"
rcvar=`set_rcvar`
: ${dnscache_enable:="NO"}
load_rc_config $name
load_svc_subr_config
run_rc_command "$1"
and a /usr/local/etc/svc.subr as attached. It's somewhat more general
than is needed for dnscache, as I also use it to start qmail.
Basically: the PROVIDE: named line is needed to get dnscache up before
ntpd, and the REQUIRE: LOGIN line needs to be changed.
