Automated `/boot` Space Manager

Problem Context

Linux power users running CachyOS or similar distros with custom kernels face frequent boot filesystem corruption. The /boot partition fills up during kernel updates, blocking critical system operations. Manual fixes (like dnf clean) only provide temporary relief, forcing users to either risk system instability or perform risky repartitioning.

Pain Points

Users waste hours monthly cleaning up /boot manually, only to face the same issue again after 3 updates. The problem escalates when kernel updates fail mid-install, leaving the system in a broken state. Current workarounds (Google searches, forum advice) are unreliable and don’t address the root cause of kernel bloat.

Impact

Downtime costs lost work hours, missed deadlines, and frustration. For professionals, this disrupts revenue-generating workflows (e.g., dev environments, servers). The risk of filesystem corruption grows with each failed update, potentially requiring a full OS reinstall—losing hours of setup time.

Urgency

The issue recurs predictably (monthly/weekly), making it a chronic pain point. Users can’t ignore it because it directly blocks critical updates. The fear of data loss from repartitioning forces them to tolerate the problem, but the risk of a catastrophic failure (e.g., unbootable system) looms.

Target Audience

Linux power users, sysadmins, and developers running CachyOS, Arch Linux, or custom-kernel distros. This includes remote workers, devops teams, and hobbyists who rely on up-to-date kernels for GPU/driver support. The problem is especially acute for users with hybrid GPU setups (e.g., NVIDIA + Intel).

Solution Approach

BootGuard is a lightweight SaaS tool that monitors and automates cleanup of the Linux /boot partition. It detects CachyOS-specific kernel bloat patterns, blocks updates when space is critically low, and provides one-click cleanup—all without requiring repartitioning. The solution runs as a background service with a web dashboard for configuration.

Key Features

1. Auto-Cleanup: Safely removes old kernels and duplicates while preserving the current bootable version.
2. Update Guard: Blocks kernel updates if free space drops below 10%.
3. One-Click Fix: Users can trigger cleanup via CLI or dashboard with zero risk of corruption.

User Experience

Users install BootGuard via CLI (5-minute setup). The tool runs silently in the background, sending notifications when /boot space is low. Before each kernel update, it checks available space and either cleans up automatically or warns the user. The dashboard shows space trends and cleanup history, so users can proactively manage storage.

Differentiation

Unlike native tools (e.g., dnf clean), BootGuard is designed specifically for CachyOS/Arch Linux kernel bloat. It prevents updates from failing in the first place, whereas manual fixes are reactive. The solution is safer than repartitioning and more reliable than forum advice. No kernel drivers or admin permissions are required.

Scalability

BootGuard scales from personal use to team environments. Teams can monitor multiple machines via a shared dashboard, and admins can set global cleanup policies. Future add-ons include disk space alerts for other partitions and integration with CI/CD pipelines for automated server updates.

Expected Impact

Users save 5+ hours/month on manual cleanup and avoid downtime from failed updates. Teams reduce risk of unbootable systems, and professionals regain confidence in their workflows. The tool pays for itself in the first month by preventing a single catastrophic failure.
