我已经使用linux有一段时间了，我已经学会了适应这个新的操作系统，所以我想改进我的配置的一些细节。
目前系统加载速度很快，但我发现它在七个部分中停止了。通过ob命令分析systemd-analyze blame，得到以下信息：

据我所知，“networking.service”服务是消耗最多时间的服务，并且根据此中的指示关联，与我的笔记本电脑的“lo”接口相关联。
我的问题是如何改进这项服务的配置，因为据我了解，接口“lo”是与我自己的笔记本电脑内部关联的接口。
OBS：我的笔记本电脑使用“Debian GNU/Linux 10 (buster)”
更新 - “cat /etc/network/interfaces”的详细信息
diego@computer:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
auto enp2s0
iface enp2s0 inet dhcp
答案1
您可能会在 enp2s0 上看到 DHCP 超时。既然您无论如何都使用 NetworkManager，我建议您只需从 中删除 enp2s0 接口定义/etc/network/interfaces，将 enp2s0 信任给 NetworkManager。
