tools: bootconfig: Add bootconfig command
Add "bootconfig" command which operates the bootconfig config-data on initrd image. User can add/delete/verify the boot config on initrd image using this command. e.g. Add a boot config to initrd image # bootconfig -a myboot.conf /boot/initrd.img Remove it. # bootconfig -d /boot/initrd.img Or verify (and show) it. # bootconfig /boot/initrd.img Link: http://lkml.kernel.org/r/157867223582.17873.14342161849213219982.stgit@devnote2 Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> [ Removed extra blank line at end of bootconfig.c ] Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
