There is no such service at the moment. For services without dependences
a "cronjob" like this will do:
* * * * * (/etc/rc.d/foo status || /etc/rc.d/foo start) >/dev/null 2>&1
Not pretty but it works.

There is another (or used to be another?) problem. Solaris tries to
start up things in parallel but doesn't have all the dependences
properly defined. So depending on the speed of your machine, disks
and eventually the network various things might not work properly
if your system comes up.
