In RG docker, can not run dhclient

[hongshengzhang]

I can't run dhclient in RG docker container, "it shows dhclient: error while loading shared libraries: libdns-export.so.162: cannot open shared object file: No such file or directory", however the so locates in the dir "/lib/x86_64-linux-gnu/" , and the path is include by /etc/ld.so.conf. Log show below

docker run --net=host --privileged --name RG -it cord/tester bash
root@ubuntu-x64:/lib/x86_64-linux-gnu# dhclient pon1_128

when I use command docker cp /sbin/dhclient RG:/usr/sbin/dhclient, the cp dhclient can work success, but there is another issue , interface pon1_128 can not get ipaddr from dhcp. From ponsim log, I can see ponsim olt has send out dhcp discovery after add double tag(4000, 128), the logs:
