从 14.10 升级到 15.04 后首次使用 systemd 启动
我从 systemd 获得这个
[ TIME ] Timed out waiting for device sys-su...m-net-devices-virbr0-nic.device.
[DEPEND] Dependency failed for ifup for virbr0/nic.
[ *** ] A start job is running for Wait for...to Quit (1h 4min 37s / no limit)
sshd已启动，因此我能够远程登录并从 复制并粘贴此内容/var/log/boot.log。我如何告诉 systemd 此接口已启动并准备就绪？
