"destroy-environment" and /var/log/juju*

[John Meinel]

I just tested again, and it looks like "strace -f" doesn't let the process
invoke sudo, if I just do "strace juju destroy-environment" it completes
fine. Though I think all the work is actually done in the sudo juju
destroy-environment call, so it may not actually be helpful.
I did find out that I can "sudo strace juju destroy-environment -y local"
so I'll include that one next.
