I have a DropDMG config and layout for my product that generates a compressed .dmg. We will refer to this as “Product.dmg”. Product.dmg is about 7.5 GB. The original uncompressed data size is about 15 GB. Everything about Product.dmg works as expected.
I need to burn Product.dmg to an 8.5 GB dual-layer DVD for distribution to my customers. I realize that I cannot burn the contents of Product.dmg directly to the DVD, because when doing so it will expand the data, which is too large to fit on the DVD. So I must burn Product.dmg as a file on the DVD instead. I am fine with that.
So what I would like to do is create a second config and layout, which we will refer to as Disc.dmg. The idea being that I still wanted a nice presentation to my customers, even if it involved an extra step. So Disc.dmg would be an uncompressed container that has a background image, and would display a special icon for Product.dmg with some text telling the customer to double-click Product.dmg to install. When the customer double-clicks on the Product.dmg icon, it opens a new Finder window with its own layout and allows the user to drag the product to their applications folder. So I essentially want to nest one .dmg within another, each with their own unique layout.
The behavior get when trying to do this is that Disc.dmg’s layout and background seems to be ignored. When I open Disc.dmg, I get a plain Finder window with the stock disc icon for Product.dmg. The background image and placement of the icon for Disc.dmg is not present.
Is what I am trying to do possible?
