There seems to be a strong interest when interviewing in this process.
- bios
- stands for: basic input / output system
- does system integrity checks
- find and runs MBR boot loader program
- mbr
- located on first sector of bootable disk
- under 512 bytes, 3 parts
- primary boot loader info (446 bytes)
- disk partition info (64 bytes)
- mbr validation check (last 2 bytes)
- contains info on GRUB
- summary: loads and exec GRUB
- grub
- kernel
- init
- runlevel
An interesting process that gets started before runlevel-initiated processes is UDEV, which gets started from rc.sysinit
