Thanks for the tip, but it still seems the end result seems like it
would be a lot of wasted time and effort uninstalling & reinstalling half
the packages on the system.  A pkg command that let me "upgrade" an IPS
package to an SVR4 package (or an oft requested IPS-on-disk format package)
without having to trawl the dependency tree and remove/reinstall all the
dependents would solve this as well, but seems like something not likely
to be as widely useful.

Unfortunately, besides having to figure out how to parse the output of
pkg uninstall -rnv, it would have to be fixed first to not throw a traceback:

(The other problem with the "migrate to custom IPS repos" plan is that right
 now I can tar up all our SVR4 packages and put them on the opensolaris
 download center for people to test - until someone sets up a
 pkg.opensolaris.org/project/ namespace or something similar for opensolaris
 projects to host their own packages on a public repo, I can only use SVR4
 packages to make test builds available to the community.)
