You can place the zone on a lofi-mounted partition. This action will limit the amount of space consumed by the zone to that of the file used by lofi. For more information, see the lofiadm(1M) and lofi(7D) man pages.
You can use soft partitions to divide disk slices or logical volumes into partitions. You can use these partitions as zone roots, and thus limit per-zone disk consumption. The soft partition limit is 8192 partitions. For more information, see Chapter 12, Soft Partitions (Overview), in Solaris Volume Manager Administration Guide.
You can use the standard partitions of a disk for zone roots, and thus limit per-zone disk consumption.
