Comment Comment by M95D I... fail to see the point of running just one process.If it's just a PoC, then:1) I remember seeing a linux firewall/gateway set up to run with just the kernel, without any userspace at all. Completely unhackable.2) To print some text or run a simple program, I belive DOS without a memory manager would be even faster.3) It takes 1s to boot linux, but an ordinary PC takes 10s to get to that linux. Even U-boot on ARM takes some seconds to load a kernel.BTW, if anyone knows any current platform that can XiP a linux kernel, please share. parent M95D 4 months ago
