Re: More details on system imaging -- livecd based proposal

I got some more things to work. To solve the issue of the netboot loop, here's what I did. Let me know if this solution is to "hacky" Since the machine booting doesn't inherently know the cobbler server or even its own name, I have it look at the kernel command line for the kickstart file. It th

I figured out why the machines weren't being rebooted, It was something to do with not unmounting the nfs share before issuing the shutdown command. I added in lines to unmount the nfs share, and now the reboot goes smoothly. The only thing left in this equation is getting it to disable netboot I

Michael, I made a few changes to my script. I changed the kernel parameter from being "save" or "load" to "cloneraction=save" or "cloneraction=load". That way it inherits properly with cobbler profiles and such. Testing things out, it seems to work very well with cobbler. I have my distro set u

Things have been going slow for me since I started classes, so sorry for the sparse updates. I never did figure out why restoring the mbr and partitions separately produced an unbootable system, and it's something I'll need to eventually solve. However, for now I've taken a step back and just foc
