Using "block_mount" mounted '/opt'
将创建的 ext4 新分区，使用 “block_mount” 以 /opt 挂载

Installed the adguardhome by these follow code:
依照如下的代码安装adguardhome:

opkg update && opkg install wget
cd /opt/
wget -c https://static.adguard.com/adguardhome/release/AdGuardHome_linux_amd64.tar.gz
tar xfvz AdGuardHome_linux_amd64.tar.gz
rm AdGuardHome_linux_amd64.tar.gz
/opt/AdGuardHome/AdGuardHome -s install

And config the openwrt by the wiki from offical web: https://openwrt.org/docs/guide-user/services/dns/adguard-home
然后再根据openwrt关于安装adguardhome的官方教程配置

And config the adugardhome (unot using DHCP).
然后再配置adugardhome（没有使用它的DHCP）

But I found that the adguardhome can't upgrade when the latest version was released.
但是，我发现当有最新版发布时，adguardhome无法更新。

另外：之前我是把新建的分区，用block_mount插件以根目录形式挂载的，那个时候是可以顺利更新的。但是我发现会导致磁盘占用越来越大，即使设置为7天，过了7天数据（日志文件？）依然会增大，并没有自动删除旧数据（日志文件？）。所以才想到以/opt挂载，结果就是adguadhome的更新又遇到了问题。
