Linux中init2对应的操作是什么？

init 2，对应的系统会运行，/etc/rc.d/rc2.d里指定的程序。

[root@localhost ~ ]# ls /etc/rc.d/rc2.d/
K01dnsmasq    K20nfs       K36mysqld      K74lm_sensors      K85rpcgssd    K89netplugd      S08iptables    S23NetworkManager  S30vboxdrv    S99local

这个级别启动的服务多了，NetworkManager/iptables/acpid/alsa都已经开启，但是nfs,smb,openvpn相关服务没有开启，这个级别不支持nfs。
