This occurs when security modules become overly aggressive during system initialization, potentially causing boot failures, readonly filesystem mounts, or service startup issues.</p> <h3 id="common-symptoms">Common Symptoms<a class="td-heading-self-link" href="#common-symptoms" aria-label="Heading self-link"></a></h3> <ul> <li>System fails to boot completely</li> <li>Filesystem mounts as readonly (<code>ro</code>) instead of read-write (<code>rw</code>)</li> <li>Critical services fail to start</li> <li>Boot hangs at specific points</li> <li>SELinux/AppArmor policy violations during boot</li> </ul> <hr> <h2 id="filesystem-readonly-issues">Filesystem Readonly Issues<a class="td-heading-self-link" href="#filesystem-readonly-issues" aria-label="Heading self-link"></a></h2> <p>One of the most common problems occurs when antivirus software causes the root filesystem to mount readonly. This prevents the system from writing critical boot files and can halt the initialization process.</p>
