 I recently installed FreeBSD 8.0-RC3 on a new system using the same
 steps as mentioned in the above guide, and I didn't have any problem
 booting FreeBSD 8.0-RC3 with the /boot/loader that was created in step
 2.6 Install ZFS aware /boot/loader.
 
 dv8t01# uname -a
 FreeBSD dv8t01 8.0-RC3 FreeBSD 8.0-RC3 #0: Tue Nov 10 06:35:19 UTC
 2009     root@mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC
 amd64
 
 dv8t01# grep zfs /boot/loader.conf
 vfs.root.mountfrom="zfs:zroot"
 zfs_load="YES"
 
 dv8t01# zpool get bootfs zroot
 NAME   PROPERTY  VALUE   SOURCE
 zroot  bootfs    zroot   local
 
 Make sure you have LOADER_ZFS_SUPPORT in your /etc/src.conf:
 
 dv8t01# cat /etc/src.conf
 LOADER_ZFS_SUPPORT=YES
