If some people grabbed an experimental carbon vm, say 3.8.10b6 or
earlier from my file servers you should be aware there is a
bug that causes the finder information to be trashed when you save an
image. This information can be restored by
two different methods:
a) Use the unix cat command
cat "imageinquestion.image" > "recovered.image"
Then open the "recovered.image" and save your image with a 3.8.9
carbon VM to restore the file type information.
The quotes are used to ensure embedded special characters or spaces
in an image name are interpreted correctly.
b) Using the mac developer SetFile command that is installed by
installing the developer tools ( or email me for a copy).
Likely you need to perform
/DeveloperTools/SetFile -a avbstclinmedz imageinquestion.image
Also see GetFileInfo, and of course the man pages
As an example a example image shows this flag usage.
