A few observations:
* All files/directories in the SuperDuper! package are world (and group) writable.
* Running the built-in updater changes the group ID of files to group staff.
* The image background in the distribution package says:
To install or update:
Drag to Applications and run!
The "Copy applications, sharing non-Apple" copy script contains:
Code:
<dict>
<key>Directive</key>
<string>symlink</string>
<key>Item</key>
<string>Applications/Utilities/SuperDuper!</string>
</dict>
Probably best for the location to be consistent?
