Issue

Reproducer:

• run Evergreen using the current docs, mounting /evergreen/jenkins/home for data
• stop the container
• run a new one
• builds are lost, registration is redone

Expected behavior

• Builds should not be lost
• The instance should be registering anew like it's a first startup

Tentative cause

This comes from mounting /evergreen/jenkins/home instead of /evergreen. Builds are under /evergreen/jenkins/var, keys (including uuid.json) are under /evergreen/keys.

Thanks to jglick for seeing this first.
