Getting so close.
Unfortunately, "My Installer.mpkg" has a custom icon. Although ditto correctly preserves the associated icon file, when expanding the archive, the custom icon bit is not set. If I put the Installer inside a folder and ditto that, it does get preserved but you end up with an extra folder level.
The solution is:
1. Create a new folder tmp
2. Copy the Installer into tmp
3. Make sure there is NOTHING ELSE in tmp (e.g .DS_Store files)
4. use ditto without the --keepParent option
ditto -c -k --sequesterRsrc tmp "My Installer.zip"
This seems to satisfy all my requirements.
Thanks to all who helped
