【问题复现步骤】
1.查看NetworkManager服务正常
构造dbus异常恢复场景:
mv /bin/dbus-daemon "$work_path"
kill -9 "$(pgrep -f /bin/dbus-daemon)"
sleep 5
busctl >/dev/null 2>&1
sleep 5
mv "$work_path/dbus-daemon" /bin/dbus-daemon
sleep 5
systemctl reset-failed dbus.service
systemctl restart dbus.service --no-ask-password --no-block
2.查看NetworkManager服务是否能够自愈
【预期结果】
NetworkManager服务可恢复
【实际结果】
NetworkManager服务无法自愈
