# Next boot will fail (boot entry points at a missing root filesystem)

- Rule ID: `boot_config_broken`
- Priority: P0
- Category: Security & Patching
- Page: https://glassmkr.com/docs/rules/boot_config_broken

## What it means

The boot entry the bootloader will select next sets a root= filesystem that does not exist on this host. The box runs now but the next reboot will strand it in the emergency shell. Fix the boot configuration before rebooting.

## 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_broken
