It has A as the root, D as a 43 * larger swap, and H as a smaller user partition. 44 * A/D/E/F: Similar to A/D/H with E and F breaking H into two partitions. 45 * E could be used for /usr and F for users. 46 * C: This gives a single, non-bootable, large user filesystem. 47 * Good for second drives on a machine (e.g. /usr/src). 48 */ 49 struct size { 50 daddr_t nblocks; 51 int cyloff; 52 }
