I have been trying to integrate LTSP-5 in fedora/ RHEL for the exactly same reasons. I have given up. Basically, the boot process is as you described it - the best way how to learn it is to unpack/mount the initrd file from Ubuntu to see how are things managed. You will see that standard Fedora/RHEL initrd file is a way simpler than the one found in Ubuntu. If you really want to spend a few days integrating this you have basically 3 options: 1. write your own initrd for RHEL that will do all the network/NFS initializations 2. take the scripts found in Ubuntus initrd to build something similar for RHEL 3. RHEL/Fedora has its own stateless Linux project - diskless Workstation - which does something similar. You could download the system-config-netboot package which does all the initrd/NFS/image things and amend it to do LTSP instead of diskless workstation.
I personally would go with the third option as it is most promising (least time spent to get things working). Ondrej David A. Kennel wrote: > Inline . . . > Jim McQuillan wrote: > >> David A.
