目前只有/etc/inittab 处理 有效点。只是启动后，暂时打印，但没有彻底断开。开机还是打印出来。
搞了一整天也不知从哪里彻底断开！多谢指导？

/etc/inittab

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
