Solaris product registry

Things I have learnt about the product registry today.

1. Some products (eg Sun Studio 12, Sun Cluster) register themselves into this mysterious registry even though they are just a bundle of standard Solaris packages.
2. To inspect and administer packages in the registry, use the prodreg command.
3. The product registry database is a flat file - /var/sadm/install/productregistry
4. If the Sun Studio installer script takes forever to start up then killing any gconftool-2 processes on a headless box will greatly speed this up.
