I'm running on Cedartrail, so this will probably work nearly as-is. Thanks. I need to use http rather then tftp, but that looks simple enough to do. I think I need to add a new image so that a SYSLINUX (or EXTLINUX) USB boot disk image gets created at the same time as the kernel / rootfs. I can do this manually, but it'll probably be worth adding it as another build option (note to self: make it usable as in installer as well). Just need to find a recipe that installs syslinux to see how to do it...
