Issue description

The nfsclient-review script sets up serverb with shares using a file in exports.d but it never does a refresh of the shares so there is nothing actually exported.

Student reported, I recreated on my lab.

Steps to reproduce:

lab start nfsclient-review

[root@servera ~]# mount -t nfs serverb:/shares /mnt

fails, permission denied

Workaround:

go to serverb as root and run an exportfs -r command (or restart nfs)

[root@serverb ~]# exportfs -r

Expected result:
