and: - rdep on iucode_tool for .install hook - USE=hostonly: iucode_tool is executed in pkg_preinst and should therefore be an idep instead of a rdep (not that it really makes a functional difference since it is bdep anyway) - rework REQUIRED_USE: the *.install hooks require the split-ucode to be present. Since with USE=dist-kernel, USE=initramfs does not install intel-uc.img (instead it is delegared to installkernel via the *.install hooks) we need always split-ucode with dist-kernel. - *.install: exit gracefully if no ucode installed this mirrors recent changes in sys-kernel/linux-firmware Signed-off-by: Andrew Ammerlaan <andrewammerlaan@gentoo.org>
