1. A method for deploying an operating system on a client, comprising:
- downloading a boot configuration file;
downloading a boot kernel and boot loader specified in the boot configuration file;
booting the boot kernel on the client;
executing the boot loader, by the kernel, to download a ramdisk image from at least one of a plurality of servers, wherein the boot configuration file is configured such that load between the at least one of a plurality of servers is approximately even during downloading of the ramdisk image; and
mounting the ramdisk image in memory on the client, wherein the ramdisk image comprises the operating system,wherein the ramdisk image is downloaded using Hypertext Transfer Protocol (HTTP) and the boot configuration file is downloaded using Trivial File Transfer Protocol (TFTP).
