Faster PXE boot
I would like to see the PXE environment streamlined so that I get to the menu screen quicker, currently this is the biggest complaint from my techs, that they have to wait too long to be able to select an option and leave the image to complete.
This request has been implemented in the SDA (K2) 4.0 release by moving to iPXE and TCP
How about setting a boot action to the machine so it happens automatically, no need to tech to wait around. Also, you could slim your KBEs somewhat by removing unnecessary drivers and have specific KBEs if you like.
