Hello. I upgraded from buildroot-2016.11.2 to 2018.02.1 and now I've a problem. I used ROOTFS_ISO9660_PRE_GEN_HOOKS to add files to iso. But now it works only with "BR2_TARGET_ROOTFS_INITRAMFS = n" and "BR2_TARGET_ROOTFS_ISO9660_INITRD = n" but I want to use initrd. What is the new way to add files to iso? Thanks, Stefan
