Docker 吃掉硬碟空間處理

•  參考 stackoverflow 的 Is it safe to clean docker/overlay2/
• 清除 ArchLinux 的 pacman cache，rumansaleem/clean-up-arch-linux.md

docker container 的 log 會無限成長，可以有好幾個 GB，只能手動刪除。

清除所有 container 的 log

# truncate -s 0 /var/lib/docker/containers/*/*-json.log

-------------------

可以設 option，限制log 的大小。

--------------------------

file: /etc/docker/daemon.json

{

  "log-opts": {

    "max-size": "20m",

    "max-file": "5"

  }

MKS 安裝非官方 image -- redrathnure / armbian-mkspi

安裝 MKS PI 官方的 image，問題實在多，例如，重新啟動後，USB 無線網卡不會動，無法自己編譯 USB網卡的驅動。

redrathnure / armbian-mkspi，提供依據 Armbian 的 build image 程序所建立專案。

可以自己建，也可以直接下載已建立的 image 來用。

若有裝 MKS LCD，啟動後，可以在 LCD 上動到啟動過程。

安裝 rtl8188gu 驅動

安裝的是 McMCCRU / rtl8188gu 的驅動。

make 時，要加上參數，"make ARCH=arm64"。

另外，os_dep/linux/ioctl_cfg80211.c 中，呼叫 cfg80211_ch_switch_notify() 時，少一個參數，修改後，即可成功編譯。

---------------------
cfg80211_ch_switch_notify(adapter->pnetdev, &chdef, 0, 0);

---------------------

但是在載入 module 時，會出現無法載入 firmware 的錯誤。

預設是安裝 armbian-firmware，/lib/firmware 下，沒有 rtlwifi/rtl8710bufw_SMIC.bin。

-----------------------

$ sudo apt install linux-firmware

[sudo] password for mks:

Package linux-firmware is a virtual package provided by:

  armbian-firmware-full 24.8.3

  armbian-firmware 24.11.1

You should explicitly select one to install.

-----------------------

若自己下載再 copy 到那個目錄下，會出現 Invalid firmware signature 的錯誤。

重新裝 armbian-firmware-full 後，就有 rtlwifi/rtl8710bufw_SMIC.bin 這個檔了。重新插拔 USB WIFI 網卡，可以正常載入 firmware。
