Some additional notes just in case:

- preinstall script with the new flat format are the equivalent of preflight script: they are always run be it a clean install or an update).

- make sure the component pkg that only contains a preinstall script is listed before the product component in the choices list. That's what determines the order of installation (usually).

Use pkgbuild to create a component pkg with your _preinstall_ script (pre_flight_ scripts are no longer supported).

Then use productbuild to build a distribution pkg containing your component pkg.

Hi there

I try to include a preflight script (a shell script that sudo removes obsolete files...) to my product archive. I build the archive using productbuild and a xml distribution definition file, and I can't find the correct way. Did anyone successfully achieve this?

Thanks in advance Eric Gorouben
