But I think you could just tell it not to use that slice or partition. I run multiple systems on my test machine, all in the same slice: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 163840 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 307*) / (-CURRENT) b: 163840 163840 4.2BSD 1024 8192 16 # (Cyl. 307*- 615*) / (3.3-STABLE) c: 4194685 0 unused 0 0 # (Cyl. 0 - 7884*) (whole disk) d: 163840 327680 4.2BSD 1024 8192 16 # (Cyl. 615*- 923*) / (3.2-STABLE) e: 614400 491520 4.2BSD 1024 8192 16 # (Cyl. 923*- 2078*) /usr (-CURRENT) f: 614400 1105920 4.2BSD 1024 8192 16 # (Cyl. 2078*- 3233*) /usr (3.3-STABLE) g: 614400 1720320 4.2BSD 1024 8192 16 # (Cyl. 3233*- 4388*) /usr (3.2-STABLE) h: 1859965 2334720 4.2BSD 1024 8192 16 # (Cyl. 4388*- 7884*) /home Note that there's no swap there; that's on a different disk. Also, you can use the same swap partition for each system, and in this configuration I use the same /home partition for each system.
