What I want to do is just launch a silent install of this package (using "installer") in my postinstall/postupgrade scripts. I'll embed the dependent package in my primary package Resources, and just launch it from the script. I'll let somebody else confirm, but I don't believe running two instances of "installer" at the same time is supported (or more appropriately, two instances of the underlying install package mechanism, "runner" or whatever it is in 10.5, is not supported). That is why if you double click 2 .pkg's in the Finder, Installer.app waits until one package is finished installing before going on to the next. It might work, but I wouldn't count on it. Why don't you want to create a metapackage? It's not that hard really-- unless you need to support 10.3 through 10.5. This email sent to site_archiver@lists.apple.com
