+# Disable automatic Ubuntu updates
Review comment:
I understand our instances typically don't run very long and automatic
updates take do not get installed immediately at start (so there is always a
time where the instance is unpatched). But currently the instance will apply
security updates, whereas after this change, the instance will always be
unpatched.
If we like to disable automatic updates, we should have a mechanism to
redeploy a patched AMI on a regular basis.
