The easiest way to create this file is to build a DMG without one, move it to a device running OSX, customize the layout, then grab the .DS_Store file for later use. That is the approach taken here. + +As of OSX Mavericks (10.9), using an Apple-blessed key to sign binaries is a +requirement in order to satisfy the new Gatekeeper requirements. Because this +private key cannot be shared, we'll have to be a bit creative in order for the +build process to remain somewhat deterministic. Here's how it works: + +- Builders use gitian to create an unsigned release. This outputs an unsigned + dmg which users may choose to bless and run. It also outputs an unsigned app + structure in the form of a tarball, which also contains all of the tools + that have been previously (deterministically) built in order to create a + final dmg. +- The Apple keyholder uses this unsigned app to create a detached signature, + using the script that is also included there. +- Builders feed the unsigned app + detached signature back into gitian. It + uses the pre-built tools to recombine the pieces into a deterministic dmg. |
