I have also no idea.
Please see both attached strace logs (linux v3.9-rc6, lxc 0.9.0).
One with lxc.autodev = 0, the other with = 1.
My lxc config:
----
lxc.network.type = empty
lxc.rootfs = /var/lib/lxc/test2/rootfs
lxc.utsname = test2
lxc.autodev = 0
lxc.tty = 4
lxc.pts = 1024
lxc.mount = /var/lib/lxc/test2/fstab
lxc.id_map = u 0 100000 10000
lxc.id_map = g 0 100000 10000
----

Thanks,
