# Note: BusyBox init doesn't support runlevels.  The runlevels field is
# completely ignored by BusyBox init. If you want runlevels, use
# sysvinit.
#
# Format for each entry: <id>:<runlevels>:<action>:<process>
#
# id        == tty to run on, or empty for /dev/console
# runlevels == ignored
# action    == one of sysinit, respawn, askfirst, wait, and once
# process   == program to run

# Startup the system
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
::sysinit:/bin/mount -a
::sysinit:/bin/hostname -F /etc/hostname
# now run any rc scripts
::sysinit:/etc/init.d/rcS
ttyO0::sysinit:/bin/sh

# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 0 vt100 # GENERIC_SERIAL

# Stuff to do for the 3-finger salute
#::ctrlaltdel:/sbin/reboot

# Stuff to do before rebooting
::shutdown:/etc/init.d/rcK
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r

基本上,這是tty的問題,因此,使用者可以在rcS執行後,先執行ttyO0::sysinit:/bin/sh除錯。

Starting logging: OK
Initializing random number generator... done.
/ #

如果還是不行的話,可以用更暴力的方式::sysinit:/bin/sh除錯。

Starting logging: OK
Initializing random number generator... done.
/bin/sh: can't access tty; job control turned off
/ #
