You say "for example", implying there is another.  I don't see it though.
What else is different?

Interesting.  Mine definately is owned by group tty, and it's not
userspace changing it after boot, since even
   lxc-start -n r2 -- /bin/sleep 100
with lxc.autodev = 1 gets /dev/tty owned by group tty.  I don't
understand why though as I don't see any place in src/lxc/conf.c where I
chown it.

Do you have the same result (just to help me figure out what's going on,
not to suggest you should have to do this) if you add

lxc.devttydir = lxc

?
