Root in an unprivileged container cannot create any devices.  You'll want
to just add something like

lxc.mount.entry = /dev/fuse dev/fuse none bind,create=file 0 0

to your container config file

> At the end of the day, I'm just trying to figure out the easiest way to share 'centralized' files (e.g., an 'uploads' folder) among my various containers.  They will all need access in the same manner nfs would be used with physical servers.
