Netboot
From Amahi Wiki
We were able to develop this integration of what used to be PXEKnife, but it's better named as Netboot, to boot multiple bootable images over the net:
Please take it for a spin:
rpm -Uvh http://files.getdropbox.com/u/364883/Amahi/amahi-netboot-0.1-5.noarch.rpm
It should not break PBA and as a little example of what this can do, we included the famous memtest86+ memory test. See if you can run it by booting off the network after you install that RPM.
If this works well, we will be able to package other things as apps that are net-bootable!
To add boot entries:
/usr/share/amahi-netboot/tftp/pxelinux.cfg/default
(This needs more documentation here!)
