It would be nice if there was a way to setup prioctl and prset right from my SMF manifest.

It is there, but in a different form. You can specify in a method context the name of the resource pool to run the service in. A resource pool is a named entity that encapsulates the above details, and is persistently maintained by the system (i.e. you don't need to manually/script recreate them on boot). In addition to providing precise control over which processors/processor sets a pool uses, they also let you construct sets anonymously -- e.g. "pool George contains 2 cpus" -- or dynamically to meet objectives -- e.g. "adjust the size of the processor set used, within the following bounds, so that the load is close to .8". See pooladm(1M)/poolcfg(1M)/libpool(3LIB) for more details. Dave
