Hello,
I would like to know whether it is possible to say tinycore at boot:
"do not bother scanning hardware devices and usb's and other things because they are the same of last time so read this file: hardware_boot_data.cfg" for example.
Is it possible? What if one is sure his/her hardware configuration will not change and wants to speed up boot process?
Thanks

Building a customized kernel tailored to measure for specific hardware would be a way to go then.
What you describe is closer to what is happening during resume from suspend-to-disk than to booting, IMHO.
-
It's different because I do not mean restoring applications state and ram data but just not to scan hardware again at boot because it seems to make the boot process pause at various points. Further, I think kernel options are useful to other than this, if I am not wrong.
-
I was purely implying the hardware related part of resuming from standby.
If you want to use a stock kernel and either disable features not needed or tweak others, then here are all the kernel parameters:

I do not understand.
Is it possible to compile a kernel and say to the compiler: "this kernel will find a sata drive hda1, an usb audio interface xyz, a nvidia card, etc?

No, depends, probably.
Those would be the most accurate short answers I could think of without consulting documentation to these three not very specific questions.
To find out what exactly is possible consult:
http://kernel.xc.net/index.cgi?version=2.6.33&arch=x86
(Use the "Help" links for items of your interest)
BTW, I have never heard of a sata drive being called hda1, something might be wrong about that.

Yes, you can custom compile your kernel for the specific hardware you have or want. I think the kernel will still scan everything even though it won't work properly without the right module. I like you idea of telling the kernel not to scan and use parameters. That'll shave off some boot time.
-
A kernel with a fixed set of hw support features is just what we're looking for.
-
Why not just delete the modules you don't need?
-
A compiled kernel with all modules built in is still faster. If you are going to take the time to delete modules(which I don't think is as simple as just delete and be done), then why take the same time to compile them in.
