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. -Greg On Mar 20, 2015, at 12:02 PM, Eric Gorouben <gorouben@gmail.com> wrote:

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
