VolumeCheck with flat packages

[Rusty Myers]

Hi all,

I'd like create a flat package that checks the OS version on the destination volume to ensure it's >= 10.9. In the past I've done this with VolumeCheck scripts in component packages. 

Is my only option to build a bundle package?

I'll admit to not being familiar with VolumeCheck scripts, but could you do the check in a preinstall script?

I haven't played with it, but I think you can do that with productbuild?

Vaughn, I tried the preinstall code, and that does work but the failure isn't very clear. It basically says the install failed, rather than the package isn't supported on this OS.

Clay, I'll check productbuild. Thanks!

This question must have come up on installer-dev a number of times and probably got answered by Stéphane :)

But for at least one working example, build a Distribution package with Packages.app and set an OS requirement - check out the distribution file that gets generated. You could likely grab some of that code and then feed productbuild your custom Distribution file with that.

The package-building script in the Munki GitHub repo also has an example of dynamically building a Distribution file with productbuild, but it doesn't contain an OS X version check script.
