the title pretty much asks the question. how do i make a portable linux from scratch that can boot on any pc regardless of the motherboard, chipset or processor. thanks!

P.S. i did build a LFS system a few months back but i have no idea on how to make it portable.

You can build the complete base system and run some of the setup triggers like tzselect, building the kernel, and such after you complete the system.

When you finish the base, just using tar to pack it up and transfer and unpack it again. Should work, but packing it might take a bit of time.

you mean i just build the LFS system on a hard drive and make an .iso image of that drive and run that iso on another system? if yes then what about the bootloader? will the bootloader be placed in the same sector of the iso image as it is on the hard drive? and if i extract the iso to the hard drive of a secondary computer will that boot up and show the LFS system that was built? thanks!

Building an iso is going to be different though. Um... You MAY want to check out the defunct LFS CD project on what to do to make a CD-ROM version of LFS. It's old, but you could use it to build a newer ISO. I think one of the CLFS projects focuses on platforms like this... embedded CLFS. But it leaves certain stuff up to you though.

Build the basic LFS and build a kernel with generic options and build drivers as modules excepting required ones. You would need some scripts to change runtime, some miscellaneous tasks as well to install grub and so on... Perhaps nobody gives exact steps or because anyone knowing enough can do it all by self.
