Partition type could be specified directly in
PARTITIONS. For example, in the partion like this:

root at vm:/vm/test # gpart show md0
=>     63  6291393  md0  MBR  (3.0G)
       63     2016       - free -  (1.0M)
     2079   110502    1  fat32lba  [active]  (54M)
   112581  6178875    2  freebsd  (2.9G)

root at vm:/vm/test # 

In the case of VM,it should be wrote in installerconfig:

PARTITIONS='vtbd0 mbr { 54M fat32lba, 3G freebsd }; vtbd0s2 bsd { 3G freebsd-ufs / }'
DISTRIBUTIONS='base.txz kernel.txz'
ZFSBOOT_DISKS=''

#!/bin/sh
