启用无人值守升级时，有谁知道这意味着什么。
sudo dpkg-reconfigure --priority=low unattended-upgrades
我的意思是说：
"origin=Debian, codename=${distro_codename},label=Debian-Security"
只需单击确定并且无人值守升级就可以了吗？
我在管理员帐户上设置的 iptables 规则是否会延续到新创建的标准用户帐户？
有没有办法验证这一点？
我应该担心 rkhunter 的这些扫描结果吗？

正如 rkhunter 报告的那样，我在 /etc/passwd 文件的末尾看到了 usermetrics 行和 clickpkg 行。
