- # The following are a series of dump format magic numbers. Each one
- # corresponds to a drastically different dump format. The first on is
- # the original dump format on a 4.1 BSD or earlier file system. The
- # second marks the change between the 4.1 file system and the 4.2 file
- # system. The Third marks the changing of the block size from 1K
- # to 2K to be compatible with an IDC file system. The fourth indicates
- # a dump that is dependent on Convex Storage Manager, because data in
- # secondary storage is not physically contained within the dump.
- # The restore program uses these number to determine how the data is
- # to be extracted.
