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). */ struct size { daddr_t nblocks;
