The documentation details in which order scripts are being run when a
metapackage is installed for the first time and when a new version (for
instance) is installed later.
The point which is strange is related to the preupgrade, preinstall
executions of script.
I'm wondering how Installer.app can know a metapackage has already been
installed and so executes the preupgrade and postupgrade scripts of the
metapackage instead of the preinstall and postinstall scripts.
Because AFAIK, the /Library/Receipts directory does not contain any
receipt for metapackage.
So how can Installer.app know a metapackage has already been installed?
Deciding this from the fact that packages within the metapackage have
already been installed may lead to incorrect conclusions since a
package can be part of 2 different metapackages.
