A bit more online reading and I found more configuration settings that look good when working with containers. So have now compiled the 4.4.45 kernel with these turned on.
Typing from my handwritten notes, here they are:
Device Drivers ->
[*] Support for multiple instances of devpts CONFIG_DEVPTS_MULTIPLE_INSTANCES
[*] Network device support ->
-*- Network core driver support ->
<*> Virtual ethernet pair device CONFIG_VETH
<*> MAC-VLAN support CONFIG_MACVLAN
In my notes, I have written that for the multiple devpts, mount with "mount -o newinstance ..."
CONFIG_VETH supports a local ethernet tunnel.
A progress note: my "next generation" Quirky, codenamed "Easy", boots to the desktop. Details to follow.

Just to confirm, I am now able to mount /dev/pts inside a container. Could not before.
# busybox mount -t devpts -o newinstance devpts /dev/pts
