I feel like we're throwing the common "it just works" case out the window to enable a very small edge case to work slightly better. I'd much rather have defaults where juju/lxd just works with most common setups. For the one little exception - if the network on your corporate LAN conflicts - we give a nice error message and give the user tools to reconfigure. Making everyone configure their network (not the easiest or friendliest task even for people on our own team), is surely going to cause us to lose a *lot* of users with a bad first impression. LXD is our code. Juju is our code. Surely we can code/configure the two to work together such that it just works for the 95% case?
