What limitations does ZENworks imaging impose on the filesystems used?

As far as I see, any filesystem can be used, but only FAT16, FAT32, NTFS, Extended2 and ReiserFS are handled at the file level. Other filesystems are copied byte by byte. This may mean that they cannot be restored to partitions that differ in size from the one they came from. And it is annoying that it cannot create just partitions, instead insisting on creating the filesystem too.
