Linux boot process:

1. boot your hardware
2. grub runs and presents you with boot prompt
3. loads kernel
4. magic
5. magic fighting evil
6. more magic
7. gdm gives you a graphical login, you login
8. magic (upon layers of magic)
9. magic (3D, even)
10. gnome presents you with a desktop.
12. run firefox
13. get email

See, Nino, It's really quite simple!

I deleted a few things for simplicity.
