Thank you!  I have generalised the patch to allow the filename to be 
specified via either the "sanboot --filename" option or the 
${san-filename} setting:

   http://git.ipxe.org/ipxe.git/commitdiff/84d406c

This generalised version allows for:

- specifying the filename directly via DHCP (as with root-path), to 
allow for boots without requiring the use of a script

- specifying the filename as part of the "sanboot" command, for a more 
natural syntax

- potential future expansion to interpret the filename for BIOS boots 
(e.g. to specify an explicit boot partition)

Thanks,

Michael
