Disklabel sits on the physical disk (wd0c, sd0c, or da0s1c) and has an internal table of partitions on this disk. Disklabel itself is a command to create these partitions.
In OpenBSD disklabel can be used interactively with disklabel -E option. This is also the same as the OS install.
OpenBSD allows 16 partitions using "disklabel wd0" shows the partition table
{drive data cut} 16 partitions: # size offset fstype [fsize bsize cpg] a: 2104452 63 4.2BSD 2048 16384 1 b: 2104515 2104515 swap c: 50331648 0 unused 0 0 d: 2104515 4209030 4.2BSD 2048 16384 1 e: 44018100 6313545 4.2BSD 2048 16384 1
This is a sample OpenBSD disklabel on a 24 GB drive. Partition a is the root disk, historically the root drive is always on a. Partition b is for swap, partition c represents the entire disk and d is /var filesystem. The rest (partition e) is for the /usr filesystem.
