/*
|
|

|
|
* CS/80 partitions. We reserve the first cylinder for a LIF
|
|
|
|
|
* style boot directory (the 8k allowed in the BSD filesystem
|
|
|
|
|
* is just way too small). This boot area is outside of all but
|
|
|
|
|
* the C partition. This implies that you cannot use the C
|
|
|
|
|
* partition on a bootable disk since the filesystem would overlay
|
|
|
|
|
* the boot area. You must use the A partition.
|
|
|
|
|
*
|
|
|
|
|
* These maps support four basic layouts:
|
|
|
|
|
*
|
|
|
|
|
* A/B/G: This is the "traditional" setup for a bootable disk.
|
|
|
|
|
* A is the root partition, B the swap, and G a user partition.
|
|
|
|
|
* A/D/H: This is a setup for bootable systems requiring more swap
|
|
|
|
|
* (e.g. those who use HPCL). It has A as the root, D as a
|
|
|
|
|
* larger swap, and H as a smaller user partition.
|
|
|
|
|
* A/D/E/F: Similar to A/D/H with E and F breaking H into two partitions.
|
|
|
|
|
* E could be used for /usr and F for users.
|
|
|
|
|
* C: This gives a single, non-bootable, large user filesystem.
|
|
|
|
|
* Good for second drives on a machine (e.g. /usr/src).
