	* opts-std-startup.c: diskfs_boot_flags -> diskfs_boot_command_line.
	(OPT_BOOT_CMDLINE): Renamed from OPT_BOOTFLAGS.
	(startup_options): --bootflags -> --multiboot-command-line
	(parse_startup_opt): Parse it.
	* diskfs.h: diskfs_boot_flags -> diskfs_boot_command_line.
	(diskfs_boot_filesystem): New macro.
	* init-main.c (diskfs_init_main): Use it.
	* init-init.c (diskfs_init_diskfs): Likewise.
	* console.c (diskfs_console_stdio): Likewise.
	* boot-start.c (_diskfs_boot_privports): Likewise.
	(diskfs_start_bootstrap): Split boot_command_line into words and pass
	those arguments to init instead of diskfs_bootflags.
	* diskfs.h: Declare it.
	* boot-start.c (diskfs_start_bootstrap, start_execserver): Use it.
	* boot-start.c (diskfs_boot_init_program): New variable.
	* diskfs.h: Declare it.
	* boot-start.c (default_init): Variable removed.
	(diskfs_start_bootstrap): Use diskfs_boot_init_program instead
	of default_init or prompting under -i.
	* opts-std-startup.c (OPT_BOOT_INIT_PROGRAM): New macro.
	(startup_options): Add --boot-init-program.
	(parse_startup_opt): Parse it.
