Before you run apt upgrade or yum update, there's a better safety net than hoping you can roll back. In this episode, Lucas and Luna dive into why filesystem snapshots — using LVM or ZFS — should be a standard pre-update ritual. They walk through a real scenario: a production server that survived a broken kernel update only because the sysadmin had a five-second snapshot routine. They explain the difference between snapshots and backups, why most sysadmins skip this step, and how to set up a simple snapshot script that takes under a minute. If you manage Linux servers and have ever held your breath during an update, this episode is for you.
