Doesn't (always) work
Authored by: mantrid on Dec 12, '06 03:41:29PM

Some preliminary observations:
Disk images created directly using hdiutil create -format UDBZ don't bunzip properly.
Those converted to UDBZ (originally created using "Disk Utility" or hdiutil without specifying a format) seem to work after bunzip2, but only using Panther's bunzip2 - Tiger's bunzip2 doesn't unzip them properly.

Anyone have any ideas to account for the differences in the UDBZ images created by the two methods, and the different behaviours of bunzip2 under 10.3 and 10.4?
