busybox: Add support for busybox-init
in config metadata we can configure busybox based init and device initializer ( mdev ) using e.g. VIRTUAL-RUNTIME_dev_manager = "busybox-mdev" VIRTUAL-RUNTIME_login_manager = "busybox" VIRTUAL-RUNTIME_init_manager = "busybox" VIRTUAL-RUNTIME_initscripts = "initscripts" VIRTUAL-RUNTIME_keymaps = "keymaps" DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit" busybox can be used to provide init system combined with mdev it makes it a complete init system for really tiny systems. This patch uses above defines to configure features in busybox to enable the init system and mdev in a configurable manner Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
