Is there a method to pre-generate a set of certificates/configuration 
files for a node?

It is not that hard to let the boot server serve the node-specific 
configuration files as a cpio (initramfs) archive, based on the 
MAC-address of the node.
The kernel supports having more than one initramfs file, and simply 
combines the files from both archives.
