What are bootimages? Bootimages are used to boot up a client over the network. The bootimage contains a Linux kernel, an initial ramdisk and a script for fetching the jobs for the client.
A client runs for first start up thru the following sequence:
- get IP, netmask, bootimage name, ... from the m23 DHCP server
- fetch the bootimage from the server with TFTP protocoll
- load and extract the image to the client memory
- start the contained kernel
- kernel loades the included initrd
- start up script fetches IP, netmask, etc. from the server again
- the script fetches the first job for the client and saves the job script file
- the script is executed and the next job will be fetched from the server
This technology makes it possible to install angelOne Linux on an empty computer. No installed operating system is needed for partition, format or installation.
