Ok so I was doing a lot of researching and was very curious about the project of porting linux to iDevices, aka iphonelinux and the openiboot project. Now here is what I'm wondering: how exactly does the port of linux work? Does it completely remove the Unix kernel and puts a linux one in place? Or is the original kernel of the iDevice kept and then linux is just ported to boot off of the kernel so in some way it's like an emulation? I am just really wanting things cleared up for me, i may sound like a noob, but please no haters thank you!
