Hello Nils, Is this for defining the "TFTP Prefix:" one usually sees in a PXELINUX boot or is it something else? Is there a specific usage scenario for it?
I'm just curious. Not much of a developer here myself, but I'm intrigued by something that helps keep PXELINUX strictly to the PXE boot scenarios that specifically require it, rather than having to bolt it on to solve funny netboot problems :) Thanks, Andrew Bobulsky On Fri, Jan 21, 2011 at 10:10 AM, Nils Carlson <[email protected]> wrote: > Add a setdirname command allowing us to retrieve the directory > from a filename.
