Im not quite sure what scyld is exactly yet. People talk about it so
often I spose I should bone up.
Is it a full os or somethign? I'd suspect if its just a cluster management
suite that you do regular old linux/unix stuff and whatever specific setup
for swapping over the network is required.
Im only familiar with FreeBSD's efforts on that however, and that seems
to be a relatively uncommon cluster platform here (for no good reason! :)
