It works now. Use notifpipe uniquely when the catch-all logger is not created. Do not use auto_string on chained stralloc

add -z option. Pass new variable to rc.init file: CONTAINER, CATCHLOG, RCINIT_CONTAINER. Handle booting inside a container

add -c option: Avoid to enable the RB_DISABLE_CAD feature at boot time. If you are coming without initramfs or by a virtualization process like lxc, this feature crash the boot. So add the ability to remove it
