There's nothing particularly safe for us to do here out of the box.
Using an alternative profile or appending to the profile (in LXD's case) is
your best bet.

Title:
Can't install kernel-nfs-server inside lxc container
Status in lxc package in Ubuntu:
Invalid
Bug description:
I'm trying to virtualize a package that depends on NFS by installing
it in an LXC container.
The commands
sudo apt-get install nfs-kernel-server
sudo lxc-create -n nfstest -t download -- -d ubuntu -r xenial -a amd64
sudo lxc-start -n nfstest
sudo lxc-attach -n nfstest apt-get update
sudo lxc-attach -n nfstest apt-get install nfs-kernel-server
should install NFS server software inside the container, but instead
fail with
...
Not creating home directory `/var/lib/nfs'.
nfs-utils.service is a disabled or a static unit, not starting it.

Presumably this is intended, and there is a way to configure lxc to allow
running nfs servers inside it (there are rumors of success on the web), but
https://help.ubuntu.com/lts/serverguide/lxc.html is silent on the issue,
and doesn't even mention the word nfs.
Likewise, https://help.ubuntu.com/lts/serverguide/network-file-system.html
doesn't even mention lxc.
