| 20 | # The following are a series of dump format magic numbers. Each one | |
| 21 | # corresponds to a drastically different dump format. The first on is | |
| 22 | # the original dump format on a 4.1 BSD or earlier file system. The | |
| 23 | # second marks the change between the 4.1 file system and the 4.2 file | |
| 24 | # system. The Third marks the changing of the block size from 1K | |
| 25 | # to 2K to be compatible with an IDC file system. The fourth indicates | |
| 26 | # a dump that is dependent on Convex Storage Manager, because data in | |
| 27 | # secondary storage is not physically contained within the dump. | |
| 28 | # The restore program uses these number to determine how the data is | |
| 29 | # to be extracted. | |

| 37 | # If there is no `=' sign, assume just checking for whether the bit is set? | |
