As DHCP bootfile can be served for any application, I think that Debian Installer should check that file is for him, not that file is for PXE... With your way, to just check for '#!ipxe' can be broken again in future once there will be another application which will use bootfile option. And it could be any fork of ipxe with new name... as it was before with gpxe... -- Pali Rohár firstname.lastname@example.org
