Using a ramdisk root

Simplicity is the ultimate sophistication. While oneSIS is capable of managing NFS-root based clusters, there are mechanisms for deploying simpler ramdisk-based root filesystems. Such minimal systems are ideal, for instance, for running cluster software such as XCPU (http://xcpu.org).

To use a ramdisk-root, simply use the 'mk-initramfs-oneSIS -ramdiskroot' option.
