How to Boot Single User Mode from the Grub Boot Loader in Solaris 10 x86 3/05 or 1/06

Applies to:Solaris Operating System - Version 10 3/05 and later
By default, in Solaris x86 10 1/06 the new GRUB boot loader does not provide a fully functional single user boot option in the menu that is presented upon booting.
The default menu only has a GRUB "Safe Mode" boot option to choose from, but not the option to choose to boot to single user mode.
A true "Single User" boot option is key for many of our customers to apply patches and perform other administration needs.
The below steps will show you the procedures to boot into single user mode using GRUB.
The first method shows how to do this temporarily, and the other shows how to do this permanently by modifying the GRUB menu.lst file.
This is also known to work with Solaris 10 3/05 and the latest Solaris 10_x86 Recommended Patch Cluster (Version May/08/06 at least) installed.
