More frequent when network comes up slower than remote storage service.

Root Cause Analysis

Blocking mount options force boot to wait on unreachable NFS endpoints.

Quick Triage

Check remote export availability and local network readiness timing.

Step-by-Step Diagnosis

Review fstab mount flags, service order, and NFS timeout behavior.
