7 # Note, BusyBox init doesn't support runlevels. The runlevels field is
8 # completely ignored by BusyBox init. If you want runlevels, use sysvinit.
11 # Format for each entry: <id>:<runlevels>:<action>:<process>
13 # <id>: WARNING: This field has a non-traditional meaning for BusyBox init!
15 # The id field is used by BusyBox init to specify the controlling tty for
16 # the specified process to run on. The contents of this field are
17 # appended to "/dev/" and used as-is. There is no need for this field to
18 # be unique, although if it isn't you may have strange results. If this
19 # field is left blank, it is completely ignored. Also note that if
20 # BusyBox detects that a serial console is in use, then all entries
21 # containing non-empty id fields will _not_ be run. BusyBox init does
22 # nothing with utmp. We don't need no stinkin' utmp.
24 # <runlevels>: The runlevels field is completely ignored.
26 # <action>: Valid actions include: sysinit, respawn, askfirst, wait, once,
29 # Note: askfirst acts just like respawn, but before running the specified
30 # process it displays the line "Please press Enter to activate this
31 # console." and then waits for the user to press enter before starting
32 # the specified process.
34 # Note: unrecognised actions (like initdefault) will cause init to emit
35 # an error message, and then go along with its business.
37 # <process>: Specifies the process to be executed and it's command line.
39 # Note: BusyBox init works just fine without an inittab. If no inittab
40 # is found, it has the following default behavior:
41 # ::sysinit:/etc/init.d/rcS
43 # if it detects that /dev/console is _not_ a serial console, it will also run:
44 # tty2::askfirst:/bin/sh
47 # Boot-time system configuration/initialization script.
48 # This is run first except when booting in single-user mode.
50 ::sysinit:/etc/init.d/rcS
52 # /bin/sh invocations on selected ttys
54 # Note below that we prefix the shell commands with a "-" to indicate to the
55 # shell that it is supposed to be a login shell. Normally this is handled by
56 # login, but since we are bypassing login in this case, BusyBox lets you do
59 # Start an "askfirst" shell on the console (whatever that may be).
62 # Start an "askfirst" shell on /dev/tty2-4
63 tty2::askfirst:-/bin/sh
64 tty3::askfirst:-/bin/sh
65 tty4::askfirst:-/bin/sh
67 # /sbin/getty invocations for selected ttys
69 tty5::respawn:/sbin/getty 38400 tty5
