Idea #13901: Module manager to improve boot time.

Written by Faryshta the 30 Sep 08 at 19:39. Related project: Xubuntu. Status: New
Rationale
I was checking from Mandriva http://blog.crozat.net/2008/09/improving-boot-time-on-general-linux.html that they are making a boot time faster to their distro. Also Windows 7 team has declared to boot in 15 seconds and to use a module intelligent manager which reduce to --40 MB-- the start of the sessions.

Something like that was promised for Jaunty but is a clear idea, if I don't have bluetooth I don't need that module running and wasting my ram. This can be a great idea at least for Xubuntu which is designed to old computer or with limited resources.

One way of handling this is a kernel module mapping program. As you could then see dependencies, which devices are bound to what, and perform other operations (if its modular enough).

This would give users the best opportunity to optimise their systems.

Vista was also supposed to boot really really fast ^^' ! I don't think we have to worry about that.

But I don't think users should have to optimise the system. We have to find a way for the OS to disable non-used modules by is own...
And to enable it again when new things are set up on the computer.

Another good read is interview with Intel developer Arjan

Mark Shuttleworth has said he targets this as a priority for Jaunty, so I'm looking forward to that already :)

Hmm, that (...)ed up the quote. Here:

There are some specific goals that we need to meet in Jaunty. One of
them is boot time. We want Ubuntu to boot as fast as possible - both in
the standard case, and especially when it is being tailored to a
specific device. The Jackalope is known for being so fast that it's
extremely hard to catch, and breeds only when lightning flashes. Let's
see if we can make booting or resuming Ubuntu blindingly quick.

I think upstart is trying to solve the whole "boot faster and better" thing.

I like this idea. Such things as battery management don't need to be run on desktops.

I agree completely. Fast booting seems to be all the hype lately, and with Linux being in the spotlight recently thanks to all MID and UMPC popularity, this is something that can win even more people!
