The platform is up, but one dependency path is not.

Use this when Linux systems boot slowly or inconsistently because multiple network authorities believe they own the active route. These issues are easy to misread because the operating system still responds while one control path, runtime dependency, or trust assumption is already out of alignment.

The symptom usually appears downstream from the real change.

• Linux assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
• NetworkManager assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
• Routing assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
• Operations assumptions are often changed indirectly by updates, policy, hardware changes, or cleanup work that looked harmless at the time.
