    Integrate these features! They know it's what we want. Why do they keep teasing?
    Because if functionality is being lost, they're not going to make it the default. Rather, they provide documentation, and leave the decision to those who can say for certain that they don't need those things.

      My MythTV backend boots Ubuntu off an SSD; I haven't timed it, but it spends noticeably more time in the BIOS than the OS boot process.

      So I don't see why Linux can't boot fast even without removing lots of services.

        I'm most certain that having an SSD would make any OS boot fast. However SSDs are still a new technology (questionable reliability) and not everyone wants or can afford one. Improving the OS's individual boot time would benefit all users.

          SSD random seek times are, at best, around 10 microseconds. So, a small, but measurable, number that adds up over the boot process.
