重现问题的操作过程

新版小小容器似乎 /proc/bus/pci/devices 权限变化了：
分别使用新版 小小容器 GXDE版 v 4.0.0 和旧版 小小电脑 GXDE版 v 1.1.0
应用的所有外部权限全部允许，在 GXDE 和 chromium 版本严格相同的情况下，出现了这些变化：

GXDE 版本：25.4.1
chromium 版本：150.0.7871.114

终端输入命令

sudo ls -Z /proc/bus/pci/devices

执行结果

新版即便是用 sudo 提权也无法访问，而旧版则可以

小小容器 v 4.0.0

ls: 无法访问 '/proc/bus/pci/devices': 权限不够

小小电脑 v 1.1.0

u:object_r:app_data_file:s0:c127,c259,c512,c768 /proc/bus/pci/devices

终端输入命令

sudo cat /proc/bus/pci/devices

执行结果

新版因权限不足拒绝打印，而旧版则正常列出了所有 PCI 设备信息

小小容器 v 4.0.0

cat: /proc/bus/pci/devices: 权限不够

小小电脑 v 1.1.0

这让某些默认以无头模式启动 chromium 的应用出现问题
新版执行命令后会反复提示：

GPU process exited unexpectedly（GPU进程意外退出）

然后 chromium 强行关闭

GPU process isn't usable. Goodbye.（GPU进程不可用）

而旧版执行命令的报错只是因为容器本身特性，最后依旧是正常运行的

终端输入命令

chromium --headless --no-sandbox

执行结果

小小电脑的容器是用tmoe做的，有对devices文件的模拟，现在的是用proot-distro做的，没有模拟devices****。下次更新我会放一个空文件到devices
