boot.mk: factor out boot/% from distro.mk Yes these bits are related to distro/ prefixed images still the overgeneralization in distro.mk didn't pay off but rather hid a bug with the only boot/isolinux in use having no dependency on use/syslinux (which is required). Maybe this will get revisited when we have other kinds of bootable images with other bootloaders (vm/ ones care for themselves as of today).

rework isoboot support beyond x86 Every .iso was assumed to be bootable since the very beginning[*], and isoboot images were deemed to be x86 isolinux ones; this didn't change with basic ppc/armh support as I never ran into hardware that would _boot_ those ISOs, not only run the code, and it was only e2k isodata project that finally forced this refactoring. It's still not perfect: pack and syslinux features still end up somewhat interwoven, and too much places care for architecture the image is being built for (instead of archdep features tossing their appropriate bits and pieces in). Should help: - any-arch regarding isodata images; - {x86,aarch64}/efi by decoupling isoboot and isolinux; - ppc{,64} as introducing yaboot support will be easier now; - mipsel{,64} too, hopefully. * I knew of school addon images baked with mkimage-profiles-desktop but postponed and then neglected the whole problem for years...
