167 * CS/80 partitions. We reserve the first cylinder for a LIF
168 * style boot directory (the 8k allowed in the BSD filesystem
169 * is just way too small). This boot area is outside of all but
170 * the C partition. This implies that you cannot use the C
171 * partition on a bootable disk since the filesystem would overlay
172 * the boot area. You must use the A partition.
173 *
174 * These maps support four basic layouts:
175 *
176 * A/B/G: This is the "traditional" setup for a bootable disk.
177 * A is the root partition, B the swap, and G a user partition.
178 * A/D/H: This is a setup for bootable systems requiring more swap
179 * (e.g. those who use HPCL). It has A as the root, D as a
180 * larger swap, and H as a smaller user partition.
181 * A/D/E/F: Similar to A/D/H with E and F breaking H into two partitions.
182 * E could be used for /usr and F for users.
183 * C: This gives a single, non-bootable, large user filesystem.
184 * Good for second drives on a machine (e.g. /usr/src).
