2. Start container
3. In container run "reboot"
4. Container comes up with with a DHCP assigned address

Thanks for reporting this bug. If you check ifconfig you'll notice the hwaddr also changes. You can specify an hwaddr in the config file with

lxc.network.hwaddr=16:73:40:b3:ef:f5

Should we simply auto-generate an hwaddr (if none is specified in the optional user-provided config file)?

Yes, I would think that we shoudl auto-generate the hwaddr. With out one, it is kind of pointless. I'll submit a patch against LXC here.
