條件有三:

1.需要在軟體包的Makefile中新增巨集定義Package/$(package-name)/preinst和Package/$(package-name)/prerm

define Package/hello/postinst
#!/bin/sh
# check if we are on real system
if [ -z "$${IPKG_INSTROOT}" ]; then
        echo "Enabling rc.d symlink for hello"
        /etc/init.d/hello enable
fi
exit 0
endef

define Package
 
/hello/prerm
#!/bin/sh
# check if we are on real system
if [ -z "$${IPKG_INSTROOT}" ]; then
        echo "Removing rc.d symlink for hello"
        /etc/init.d/hello disable
fi
exit 0
endef

2.需要一個啟動指令碼,並且需要有執行許可權(曾嘗試過直接將指令碼放置在target/linux/$(chip-series)/base-files/etc/init.d目錄下,但是openwrt啟動後不會執行這個指令碼，為什麼，因為沒有執行許可權

將啟動指令碼製作成一個此軟體包的補丁，放到軟體包的patches目錄下,指令碼內容如下:

#!/bin/sh /etc/rc.common
# "new(er)" style init script
# Look at /lib/functions/service.sh on a running system for explanations of what other SERVICE_
# options you can use, and when you might want them.
 
START=200
APP=hello
SERVICE_WRITE_PID
 
=1
SERVICE_DAEMONIZE=1
 
start() {
        service_start /usr/bin/$APP
}
 
stop() {
        service_stop /usr/bin/$APP
}

3.指令碼準備好了,那麼此時需要安裝指令碼到要製作的根檔案系統中

在軟體包的Makefile中的巨集定義Package/$(package-name)/install里加入以下類似程式碼:

$(INSTALL_DIR) $(1)/etc/init.d

$(INSTALL_BIN) $(script-path) $(1)/etc/init.d

這樣許可權就有了
