操作系统：NixOS 不稳定应用程序：minidlna

我在 Debian 和我的电视上成功地使用了 minidlna。但是我在使用 NixOS 时遇到了问题。

这是我的 NixOS 配置 ( /etc/nixos/configuration.nix):

#DLNA
services.minidlna.enable = true;
services.minidlna.settings = {
  friendly_name = "PCMEDIA";
  media_dir = ["V,/mnt/ORION/DLNA/"];
  log_level = "debug";
};

这是我尝试用电视连接到 DLNA 服务器时的日志：

$ sudo journalctl --unit minidlna -r

如何让 minidlna 发挥作用？不仅仅是我的电视，它不适用于 VLC 或任何其他支持 DLNA 的应用程序。

我正在使用另一个 dns 解析器，blocky并将其与systemd-resolved. blocky已经具有缓存和预取等功能。所以我不想systemd-resolved运行缓存并弄乱blocky' 的预取。但是如何禁用 systemd-resolved 的“缓存”？

配置文件：

/etc/systemd/resolved.conf.d/dns.conf

[Resolve]
#blocky
DNS=127.0.0.10

DNSSEC=yes

# how to disable cache?
cache=no 

FallbackDNS=84.200.69.80 8.8.8.8 2001:1608:10:25::9249:d69b 2001:4860:4860::8844

Domains=~.

设置cache=no没有效果。systemd-resolved统计数据：

❯ systemd-resolve --statistics
DNSSEC supported by current servers: yes

Transactions              
Current Transactions: 2
  Total Transactions: 4008
                          
Cache                     
  Current Cache Size: 189
          Cache Hits: 1044
        Cache Misses: 3072
                          
DNSSEC Verdicts           
              Secure: 230
            Insecure: 410
               Bogus: 731
       Indeterminate: 0

PS：我可以直接使用blocky但systemd-resolved在各种网络场景下处理DNS更好。

我正在使用firewalld。我想在受信任区域中添加一系列源 IP。我实际上可以这样做：

❯ sudo firewall-cmd --zone=trusted --add-source=192.168.0.0/16
success

我可以确认这些规则是有效的。但是我不想在每次启动计算机时都这样做。所以我想让规则永久化，但这不会发生：

❯ sudo firewall-cmd --runtime-to-permanent
Warning: NOT_ENABLED: ens32
success

❯ sudo firewall-cmd --get-active-zones
public
  interfaces: ens32

当我重新启动时，规则不再存在，我必须再次添加它们。

有没有办法使规则永久化firewalld？
