* Since the SCSI standard tends to hide the disk structure, we define
* partitions in terms of DEV_BSIZE blocks. The default partition table
* (for an unlabeled disk) reserves 512K for a boot area, has an 8 meg
* root (A) and 32 meg of swap (B). The rest of the space on the drive
* goes in the G partition. As usual, the C partition covers the entire
* disk (including the boot area).
*
* We also define the D, E, F and H partitions as an alternative to B and G.
* D is 48Mb, starts after A and is intended for swapping.
* E is 50Mb, starts after D and is intended for /usr.
* F starts after E and is what ever is left.
* H starts after D and is what ever is left (i.e. combo of E and F).
