BOOT PROCESS BREAKDOWN 1) The boot command reads and loads the bootblock into memory. 2) The bootblock locates and loads the secondary boot program, ufsboot, into memory and passes control to it. NOTE: A network boot uses a different secondary boot program: inetboot instead of ufsboot. 3) ufsboot locates and loads the core kernel images and the required kernel runtime linker (krtld) into memory and passes control to the loaded kernel. 4) The core kernel locates and loads mandatory kernel modules from the root disk directory tree and executes the main startup code. 5) The kernel startup code executes, creating and initializing kernel structures, resources, and software components. 6) The system executes shell scripts from system directories, bringing the system up to the init state specified in the /etc/inittab file.
