清除Ubuntu的垃圾檔案

小筆電的空間又不夠了

需要清除一下空間才行了

網路上參考這些指令

sudo apt-get autoclean 清理旧版本的软件缓存
sudo apt-get clean 清理所有软件缓存
sudo apt-get autoremove 删除系统不再使用的孤立软件

尤其是最後一個

讓我多了120MB的空間

Welcome to Buildroot

Qi - another bootloader on linux

Luke介紹
是一個輕量bootloader替代方案(相對於u-boot)

Luke說它支援SD card
所以如果你的flash太小
使用這個bootloader可以把OS放到SD卡啟動
