This tag covers both bootloader issues (what happens before the operating system starts) and the starting up of the operating system.
However, I think since this excerpt was written almost two years ago we've mostly been using boot for bootloader issues (up to loading the kernel) and startup for the OS startup (
init, rc scripts and so on). I think we should make this distinction official, and retag the few questions that will then be mistagged. Any opposition?
Also, on which side of the fence do initrd issues fall?
