Ok...

lxc-start 1392374433.579 DEBUG    lxc_conf - Bind
mounting /dev/.lxc/user/fedora1.533098688727054a
to /usr/lib64/lxc/rootfs/dev

That looks good...

lxc-start 1392374433.579 INFO     lxc_conf - Mounted /dev
under /usr/lib64/lxc/rootfs
lxc-start 1392374433.579 INFO     lxc_conf - Creating initial consoles
under /usr/lib64/lxc/rootfs/dev
lxc-start 1392374433.579 INFO     lxc_conf - Populating /dev
under /usr/lib64/lxc/rootfs
lxc-start 1392374433.579 ERROR    lxc_conf - Operation not permitted -
Error creating null

That looks bad.  Rats.  That's not going to work for the reason I
suspected to begin with.  We're back to square one and need to get the
operations of mounting devpts on top of tmpfs working.
