# Boot configuration drift (a future or fallback boot could strand this host)

- Rule ID: `boot_config_drift`
- Priority: P3
- Category: Security & Patching
- Page: https://glassmkr.com/docs/rules/boot_config_drift

## What it means

This host boots correctly now, but a boot reference (the kernel-cmdline source, the default entry, or a fallback entry) points at a wrong or absent filesystem. A future kernel update or a fallback boot could drop it to the emergency shell. Fix before the next kernel update.

## Remediation

Every rule ships a distro-aware remediation workflow: prerequisites, the
command to run, how to verify it worked, and how to roll it back. Those are
instructions for an operator. Glassmkr does not execute them for you.
The workflow for this rule is on its page: https://glassmkr.com/docs/rules/boot_config_drift
