I would love to see this feature added to CentOS/RHEL. In the past, we used NFS Diskless which is anything but diskless. Hacking together an initrd that loads everything into ram is, well, hacky. To have a dracut function or a toggle to enable this would be great for lightweight deployments, testing, labs, vagrant, etc... I'm sure that RHEL must have been contemplating it because there is /etc/sysconfig/readonly-root unless that was just a better way to do NFS diskless...
