   Converting from grub to /boot
   -----------------------------
   
   These instructions are provided only to help people using grub, which
   used to be the normal approach.
   
   These instructions were used to convert a system from
   grub to /boot.  The system was originally installed in February of
   2006 with a RAID1 setup and grub to boot Xen 2, and has been updated
   over time.  Before these commands, it was running NetBSD 6 i386, Xen
   4.1 and grub, much like the message linked earlier in the grub
   section.
