- mkinitrd() calls make-boot-splash after building the initrd
(since /sbin/mkinitrd doesn't do it anymore) - change mkinitrd() parameters - change add_kernel() parameters and add option b_no_initrd (it is available in installkernel though i suspect it is unused) - after reading config file, get {perImageAppend} and {default_vga} (it was only done for lilo and {perImageAppend}) - keep the current kernel for linux-nonfb too (it was only done for failsafe) - add create_link_source(), action(), when_config_changed_{lilo,grub,yaboot} - create write_yaboot()
