為 snapd 配置 Linux 核心

我正在嘗試在 gentoo 上安裝 snapd 並收到以下錯誤：

$ sudo emerge snapd

誰能幫我如何配置linux核心snapd！

錯誤消息說：

* Checking for suitable kernel configuration options...
*   CONFIG_SECURITY_APPARMOR:   is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.
* Once you have satisfied these options, please try merging
* this package again.

這表明該軟體包依賴於核心配置選項CONFIG_SECURITY_APPARMOR，並且未設置。您需要重新配置核心以啟用該選項，重建核心，重新啟動（或載入相關模組），然後再次嘗試安裝軟體包。
