menuconfig PREINITOPT
bool "Preinit configuration options" if IMAGEOPT
default n
help
These options are used to control the environment used to initialize
the system before running init (which typically mean /sbin/init which
switches to multiuser mode).
config TARGET_PREINIT_SUPPRESS_STDERR
bool "Suppress stderr messages during preinit" if PREINITOPT
default y
help
Sends stderr to null during preinit. This is the default behaviour
in previous versions of OpenWRT. This also prevents init process
itself from displaying stderr, however processes launched by init
in multiuser through inittab will use the current terminal (e.g.
the ash shell launched by inittab will display stderr). That's
the same behaviour as seen in previous version of OpenWRT.
config TARGET_PREINIT_TIMEOUT

default n
help
Show preinit all network messages (via netmsg broadcast), not only
the message indicating to press reset to enter failsafe. Note that
if the architecture doesn't define an interface, and there is no
'Preinit network interface' defined, then no messages will be
emitted, even if this is set.
config TARGET_PREINIT_SUPPRESS_FAILSAFE_NETMSG

prompt "Suppress network message indicating failsafe" if PREINITOPT
default n
help
If "Show all preinit network messages" above is not set, then
setting this option suppresses the only message that would be
emitted otherwise, name the network message to enter failsafe

help
Interface for sending preinit messages to network, and any other
default networking in failsafe or preinit. If empty

default n
help
These option choose the command that will run as the 'init' command
(that is which is responsible for controlling the system once preinit
transfers control to it) as well as some options controlling its
behaviour. Normally init is /sbin/init.
config TARGET_INIT_PATH

prompt "PATH for regular boot" if INITOPT
default "/bin:/sbin:/usr/bin:/usr/sbin"
help
Default PATH used during normal operation
config TARGET_INIT_ENV

default ""
help
Should be a space seperated list of variable assignments. These
variables will be present in the environment. Spaces may not be
present (including through expansion) even in a quoted string
(env doesn't understanding quoting).
config TARGET_INIT_CMD
string
prompt "Init command" if INITOPT
default "/sbin/init"
help
The executable to run as the init process. Is 'exec'd by
preinit (which is the init that the kernel launches on boot).
config TARGET_INIT_SUPPRESS_STDERR
bool
prompt "Suppress stderr messages of init" if INITOPT
default y
help
Prevents showing stderr messages for init command if not already
suppressed during preinit. This is the default behaviour in
previous versions of OpenWRT. Removing this does nothing if
stderr is suppressed during preinit (which is the default).
