Questions

## Packer: frequently asked

Why build images instead of configuring servers at boot?

Baked images start faster and behave the same every time. Boot-time configuration can fail when a package source is down just as you need to scale.

How often should images be rebuilt?

At least whenever security updates are released for the base system. We automate rebuilds so this happens without anyone remembering.
