How does the boot process[init levels] work on Linux? How
is it different from Solaris?

Answer Posted / sanjay

1. The system BIOS checks the system and launches the first
stage boot loader on the MBR of the primary hard disk.

2. The Frist stage boot loader loads itself into memory and
launches the second stage boot loader from the /boot/
partition.

3. The second stage boot loader loads the kernel into
memory, which in turn loads any necessary modules and
mounts the root
partition read-only.

4. The kernel transfers control of the boot process to the /
sbin/init program.

5. The /sbin/init program loads all services and user-space
tools, and mounts all partitions
listed in /etc/fstab.

6. The user is presented with a login screen for the
freshly booted Linux system.
