CM diskless node initrd
From ComputeMode
Now that the Linux kernel is booting with its attached initrd, the following events take place:
- try to find and load a valid network card driver: all the previous network communications happened through the UNDI network stack, which stands for Universal Network Device Interface and is basically a low-level, low-performance interface available for early network communication - it may not be used by modern OS
- try to get a DHCP address from the CM server
- set up the disk-less Linux distribution by using a mix of NFS mounts and RAM disks
- start the distribution processes and services
