Packager Images for Mac DMG and PKG Backgrounds

[Scott Palmer]

As I continued my search I gained a better understanding of the packager code and see that the file name is in fixed for both DMG and PKG bundlers to use the same “-background.png” suffix.

:-(

This is done in the getConfig_BackgroundImage method of the PKG bundler and the getConfig_VolumeBackground method of the DMG bundler.

It should be fixed as otherwise you can’t run all bundlers in a sane way with customizations.

Regards,

Scott
