ZFSRoot installation, FreeBSD 9.0R.
GPT partition.
VmWare ESXi 4.1.

Long delay (more 30 seconds) on loader disk detect.
Debug print pointed to zfs/zfs.c:zfs_dev_init.
This function found disk0 and walked over 128 potencial slices, trying
'p' slice and 's' slice. Each attempt -- 1/4s (and nothing found).

How to speed up boot?
