fedora-nm-boot-slow

fedora-nm-boot-slow is a skill for Claude Code from rhtevan/agentfs. It costs 33 tokens per session (2,142 once invoked), scanned B, original, Apache-2.0.

A troubleshooting guide for slow Fedora startup caused by NetworkManager-wait-online.service. This system service waits for network connections before allowing later startup tasks to run.

In plain words
What is it for?
Use it to inspect boot timing and network dependencies, then follow remediation steps for the delay.
Why use it?
It helps identify when a slow wired or Wi-Fi connection is holding up the whole boot process and delaying dependent applications.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

fedora-nm-boot-slow scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Fedora NM Boot Slow

Diagnoses and guides remediation of slow boot caused by NetworkManager-wait-online.service blocking the systemd boot sequence. This service waits for ALL auto-connected network interfaces to finish activating before releasing network-online.target — which delays everything downstream (VPN clients, log forwarders, and desktop apps that start after network is ready). The most common root cause on laptops/workstations is having both wired and Wi-Fi auto-connecting simultaneously, where the slower Wi-Fi path (scan → WPA handshake → DHCP) holds up the entire boot.

Prerequisites

  • Fedora 40+ with NetworkManager as the network manager
  • systemd-analyze available (standard on Fedora)
  • nmcli available (standard with NetworkManager)
  • sudo access for remediation steps (diagnosis is sudo-free)

Steps

1. Diagnose Boot Time

First, check whether NM-wait-online is actually a significant bottleneck in the current boot:

systemd-analyze blame | head -20

Look for NetworkManager-wait-online.service near the top of the list. Also check the critical chain:

systemd-analyze critical-chain

If NetworkManager-wait-online.service appears in the chain with a + time of 3 seconds or more, it is a meaningful bottleneck.

2. Identify Auto-Connected Interfaces

Find which network interfaces auto-connect at boot:

nmcli -f NAME,TYPE,DEVICE,CONNECTION-FLAGS con show

Look for connections with autoconnect in the flags or check explicitly:

nmcli -f NAME,TYPE,connection.autoconnect con show | grep yes

Note the names of any Wi-Fi connections with autoconnect: yes. These are candidates for the slowdown if wired is also auto-connecting.

3. Check What Depends on network-online.target

Understand the blast radius — what services are blocked at boot:

systemctl list-dependencies network-online.target --reverse

Only active (● green) services matter. Inactive (○ grey) services are not running and have no impact.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fedora-nm-boot-slow is a skill published in the GitHub repository rhtevan/agentfs (2 stars, last pushed today), licensed Apache-2.0. It adds 33 tokens to every session and 2,142 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
