在 ubuntu 22.04 上，我尝试停止并禁用 systemd-resolved：
sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo systemctl status systemd-resolved
○ systemd-resolved.service - Network Name Resolution
Loaded: loaded (/lib/systemd/system/systemd-resolved.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:systemd-resolved.service(8)
man:org.freedesktop.resolve1(5)

但流程仍在进行中：
ps auxw | grep resolved
systemd+ 166263 0.0 0.0 23964 12648 ? Ss mai28 0:12 /lib/systemd/systemd-resolved
systemd+ 166266 0.0 0.0 23932 12672 ? Ss mai28 0:00 /lib/systemd/systemd-resolved
systemd+ 166271 0.0 0.0 23932 12636 ? Ss mai28 0:34 /lib/systemd/systemd-resolved
systemd+ 166272 0.0 0.0 23932 12692 ? Ss mai28 0:03 /lib/systemd/systemd-resolved
即使我杀了他们：
sudo killall systemd-resolved
它立即返回：
ps auxw | grep resolved
systemd+ 253920 0.5 0.0 23964 12488 ? Ss 15:04 0:00 /lib/systemd/systemd-resolved

systemd+ 253929 0.5 0.0 23932 12692 ? Ss 15:04 0:00 /lib/systemd/systemd-resolved
gquentin 253934 0.0 0.0 17880 2380 pts/1 S+ 15:04 0:00 grep --color=auto resolved
那是什么原因呢？
问候，Gaétan
