Bug Description
When Ubuntu is booting, the progress bar is not moving smoothly. When the booting process is at 50%, the progress bar does not show 50%. If anyone knows what part of the system decides how much % the progress bar shows, please tell me.

If you are asking what I think then this is very difficult and probably worthy of a PhD. The problem is you don't know how long each individual section is going to take because it is dependent on the hardware and the system's state so you just go by the number of tasks. If you have are booting off USB then a particular part may go very quickly because it's seeky. If you have a fast CPU then another part may go quickly because it was processor bound. Different hardware, software configuration and disk layout will take varying amounts of time. One idea from someone in the lab was to do timing tests based on hardware and try and match it up to similar hardware but this was highly speculative and is it stands it doesn't sound practical.
If what you meant was smooth movement inbetween discrete sections (e.g. slide then stop, slide then stop) please disregard the above and add a comment noting as much.
