You mean in the commit log, or on the list ?

Basically, what i am doing is the following :

Here is the unit file ( copy from nginx, as I cannot include it sine
ExecStart cannot be replaced ) :

Description=Test of a specific nginx running in lxc
After=syslog.target network.target remote-fs.target nss-lookup.target

ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.%i.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.%i.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID


And to run it :

# virt-sandbox-service  create -u nginx_lxc@  test.example.org --package

So this create a container using /etc/nginx.test.example.org.conf as a
configuration file, with the unit being linked and properly templated
( http://0pointer.de/blog/projects/instances.html ).

If that's enough explanation, I will write something in the commit log,
and also add some documentation as I totally forgot about it.
