如何改变dhcp启动的顺序？

drycony

问题是这样的，我在fstab里添加了一个网络分区

root@cubieboard4:~# cat /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM
/dev/sda1       /ptdownload     ext4    defaults         0       0
//192.168.31.1/XiaoMi/PTDownLoad /xiaomi cifs defaults,username=root,password=111111  0 0

每次开启启动都没有挂载成功，看了开机日志，大概原因是挂载网络分区时，系统的网卡还没有获取到ip。所以如何调整这个dhcp启动的顺序呢，让挂载前就获取ip地址。。
