Oddly, there didn't appear to be one; "find /var/log -name \*lxd\*" just 
found "/var/log/lxd".  Nothing relevant-looking in "/var/log/upstart/" 
apart from "lxc-net.log", which has an "Address already in use" error:

     dnsmasq: failed to create listening socket for 10.0.3.1: Address 
already in use
     Failed to setup lxc-net.

Doubly-oddly, there's a "/etc/init/lxd.conf" *and* a "/etc/init.d/lxd", 
which confuses me a little.  Does that not mean that both init and 
upstart will try to start it?  (My knowledge of the workings of init 
systems in not as in-depth as I would like.) Should I remove one of them 
then change the remaining one to write stdout/err somewhere sensible?

I can also see that there are still init and upstart scripts for lxcfs, 
which is a bit messy -- the "apt-get remove lxcfs" should presumably 
have deleted them -- but they depend on "/usr/bin/lxcfs", which 
definitely doesn't exist, so I guess that's not the problem.


All the best,

Giles
