As long as its configure(able) IMO seems like it should be fine. One
nice thing right now is that all of a containers stuff (config and
rootfs) is under one directory (in $LXCPATH/<container name>), which
makes moving it to another machine easy. This seems more like the
"appdirs" idea than "the unix way" (/etc and /var), so for "appdirs"
style I'd expect the logs to be in $LXCPATH/<container name>/logs/
rather than /var/log/lxc/<container name>.log. Of course a unix person
would probably first think to look in /var/log/lxc :)
