Hi all,

I got the crazy idea to boot my servers purely from netboot with their root filesystems being initramfs archives coming from tftp on pxeboot.

Is this reasonable? I tried just passing a cpio of my desired root partition as the initrd option, but it ended up using my hdd as root, I think because my initramfs didn't have a file at /init. Everyone else seems to just use their initramfs in order to boot something else, like nfs, but I've got plenty of RAM and don't really want to introduce the additional complexity and latency of NFS.

Anyone done anything like that?

Thanks,
Peter
