Hi, I'm setting up a cluster filesystem on debian, there's lot of typing to get everything works, and more importantly I don't want to waste a hard drive for the operating system cause each machine will have 4G of ram, I just like to load everything into the memory and mount all hard drives as pure storage node, all logs will goes to /dev/null or logrotate.
So, is there a nice way to boot from network into memory, or create a livecd that get everything into the mem after boot ?
thanks

Re: creating livecd/booting from network/everything on RAM
You can have everything in RAM by putting it on an initrd. But you might as well network boot from an NFS root filesystem since the kernel caches things into memory automatically.romerun wrote:So, is there a nice way to boot from network into memory, or create a livecd that get everything into the mem after boot ?
I suggest you take a look at initramfs-tools (for network boot) and debian-live (for read-only filesystem). See http://debian-live.alioth.debian.org/
They have a netboot image up for download.
