这样相较于 Arch 原生运行 Steam 有什么优势吗？Steam Deck 的 Steam OS 都基于 Arch Linux 了😂

1. 运行环境隔离，宿主机不需要开 multilib 仓库；
2. （借助 Btrfs 子卷）方便快照和迁移；
3. 文件系统隔离，不会污染真实家目录。

总的来讲，只要是「跟滚动更新发行版格格不入」的大型（专有？）软件基本都适合放进容器垃圾桶。

很好，皓奇老师。

好奇老師的容器什麼時候換成 ubuntu 了（還是本來就是（

[liolok]

一个月前换的，以为是之前的 Arch 容器里面出了什么问题（貌似也的确有点问题，包管理记录全无了）索性换了一下。

Arch 容器不滚终究还是怪怪的，Uuu 2004 可以官方源直装 Steam 也算是体验了一下，而且之后也不用再管容器里的系统环境了。

我没跑起来来，不确定是哪里出了问题

你好！我之前在用 A 卡，也是最近换了 N 卡才发现有坑，有两点：

1. 宿主内核版本跟容器驱动版本需要相符，之前用 mesa 就没什么感觉，容器内的版本老很多大概也没问题；
2. /dev/nvidia* 大概全都需要挂载才行，.nspawn 文件里不太能写脚本逻辑，所以大概需要硬编码一下。

（擅自整理了一下你的评论里的代码块，收纳一下读起来更方便。）
