cobbler 無法同步到我添加的 repo

我將 centos 基礎 repo 添加到 cobbler：

cobbler repo add --arch=x86_64 --name=Centos-Base --mirror=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra

但執行 cobbler reposync 失敗：

   main()

這不是那樣工作的，因為 Cobbler 無法處理鏡像列表功能。該--mirror選項必須指定您要從中下載儲存庫的特定 URL。
