Transition from the old mountroot setup to the new zfsboot x86 in snv_62.

1. Assume the system is boot up on a ZFS root using the old mountroot setup.

2. Remove the following entries in /etc/system:

   (delete from /etc/system)
   rootfs:zfs
   zfsroot:rootpool/rootfs 
   

3. BFU to snv_62+.

4. Copy /boot/grub/menu.lst to your top level rootpool filesystem since that is where GRUB will read the menu.lst from:

   # mkdir -p /rootpool/boot/grub (assuming rootpool is mounted on /rootpool)
   # cp /boot/grub/menu.lst /rootpool/boot/grub
   

5. Edit /rootpool/boot/grub/menu.lst to include an entry for booting up your ZFS root filesystem:

   title Solaris ZFS
   bootfs rootpool/rootfs
   kernel$ /platform/i86pc/kernel/unix -B $ZFS-BOOTFS,console=ttya
   module$ /platform/i86pc/boot_archive
   

6. Install the new bootloader, assuming ZFS rootpool is on c0d0s3:

   # installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0d0s3
   

7. Reboot. Remember to change the boot device in BIOS to where the rootpool is and select your ZFS Boot entry from the GRUB menu.
