| 12 | # <id>: WARNING: This field has a non-traditional meaning for BusyBox init!
|

| 13 | #
|
|---|
| 14 | # The id field is used by BusyBox init to specify the controlling tty for
|
|---|
| 15 | # the specified process to run on. The contents of this field are
|
|---|
| 16 | # appended to "/dev/" and used as-is. There is no need for this field to
|
|---|
| 17 | # be unique, although if it isn't you may have strange results. If this
|
|---|
| 18 | # field is left blank, then the init's stdin/out will be used.
|
|---|
| 19 | #
|
|---|
| 20 | # <runlevels>: The runlevels field is completely ignored.
|
|---|
| 21 | #
|
|---|
| 22 | # <action>: Valid actions include: sysinit, respawn, askfirst, wait, once,
|
|---|
| 23 | # restart, ctrlaltdel, and shutdown.
|
|---|
| 24 | #
|
|---|
| 25 | # Note: askfirst acts just like respawn, but before running the specified
|
|---|
| 26 | # process it displays the line "Please press Enter to activate this
|
|---|
| 27 | # console." and then waits for the user to press enter before starting
|
|---|
| 28 | # the specified process.
|
|---|
| 29 | #
|
|---|
| 30 | # Note: unrecognized actions (like initdefault) will cause init to emit
|
|---|
| 31 | # an error message, and then go along with its business.
|
|---|
| 32 | #
|
|---|
| 33 | # <process>: Specifies the process to be executed and it's command line.
|
|---|
| 34 | #
|
|---|
| 35 | # Note: BusyBox init works just fine without an inittab. If no inittab is
|
|---|
| 36 | # found, it has the following default behavior:
|
|---|
| 37 | # ::sysinit:/etc/init.d/rcS
|
|---|
| 38 | # ::askfirst:/bin/sh
|
|---|
| 39 | # ::ctrlaltdel:/sbin/reboot
