在我们学院，我们拥有大多数新 Ubuntu 发行版的镜像，以节省更新成本。我们想将 rabbitvcs 添加到计算机中，但可以通过 PPA 而不是官方 repo 获得。那么可以将 PPA 添加到 ubuntu 存储库的（私有）镜像中吗？

PS：我想听听所涉及的技术和法律问题。

我的 ubuntu (jaunty) 系统最近因这条踪迹而崩溃。我可以从这个踪迹中推断出什么信息？我通过 ssh 登录，并试图连接到 wifi 网络。ath_tx_start 听起来像是 madwifi 驱动程序中的一个函数。我应该在哪些位置搜索以找到进一步的痕迹，网络上是否有一些地方可以找到有关崩溃的帮助？

编辑：我刚刚发现机器上的处理器是geode处理器并且不支持PAE，并且我已经安装了ubuntu服务器附带的默认内核（使用PAE）。这会导致崩溃吗？
