The following NEW packages will be installed:

libevent-1.4-2 libgssglue1 libnfsidmap2 librpcsecgss3 nfs-common portmap ucf

Additional mount points can be added. NFS can be done, but it was found that in addition to the lxc container, the nfs server should also export to the lxc host, even if the host does not nfs mount the filesystems.
