Boot
什麼是邪惡的在啟動過程中花了這麼長時間？
這是 openSUSE 13.2 上的 wicked 0.6.12 和 systemd 210。未安裝網路管理器。網路介面配置有靜態 IPv4 地址。普利茅斯沒有安裝，因為我更喜歡看看發生了什麼。
開機時間長的離譜。在圖形目標出現之前，系統只是坐在那裡顯然什麼都不做。

DHCP 超時需要很長時間。編輯和更改和
/etc/sysconfig/network/dhcp的值。DHCLIENT_WAIT_AT_BOOT``DHCLIENT6_WAIT_AT_BOOT
嘗試執行
systemd-analyze critical-chain。我認為輸出比日誌更容易閱讀。好吧，它可能只是證實 wicked 是罪魁禍首。我還沒有 wicked 的經驗，但我會嘗試在 strace 下啟動它以查看它掛起/超時的位置，或者並行執行 tcpdump 以查看它試圖在網上做什麼。編輯：哎呀，我錯過了你的情節連結。所以我猜關鍵鏈確實只會表明 wicked 是罪魁禍首……所以試試 strace 和/或 tcpdump。
Edit2：使用 strace 我會嘗試
ExecStart=/usr/bin/strace -ff -o /tmp/wicked.str -ttt -T /usr/sbin/wicked --systemd ifup all在邪惡的單位文件中。
