This is forceNew?

[nat-henderson]

It is! Descriptions go that way most of the time. It's nuts.

My unit test is running into quota issues, so I'm going to submit since running "terraform apply" with this test's config worked during development. If the test fails in the nightly I'll fix it from there.

[nat-henderson]

Ah, shoot, sure.
