what happens when a LiveCD boots up?
I'm in the process of making a live cd. I'm making the cd etc and I would just like some pointers about what each file does.
I understand that the initrd file contains the root directory which then gets loaded onto /dev/ram0.
How big should this be? MOst things I have read say that it should be only 4mb.
What happens if the root directory is larger than 4mb (which it will be). Surely I don't mount 500mb into my RAM! that would be a waste.
Could someone please explain to me what happens when a live cd boots (normally). That is, what happens to the initrd file, where does the rest of the / (root) directory live? WHat hsould I really put in the initrd file? (at the moment I have busybox and tinylogin)
Many thanks in advance
