結果根本沒被壓縮...
btrfs會用某個演算法判斷要不要壓縮...可是詳情不太明白
沒辦法只好把那個tar的內容展開...
發現只用了1.9GB...效果似乎還能接受...
雖然同樣的檔案用reiser4的gzip壓縮只要花1.7GB

btrfs的fsck工具還很陽春...沒有支援完整的fsck.*的介面
所以開機的時候自動fsck會失敗 = =

Linux領域一直缺少一個"好的"可以壓縮的檔案系統現在終於有了
雖然還是有點實驗性質的東西...
不過可以進官版kernel就代表已經有一定的品質了吧?

準備把portage tree等不重要的東西往裡面塞

不過, 這個 beyond-sources 到底 patch 了什麼? 有點怕怕

我暫時先讓他壓 /usr 跟 /opt 兩個程式檔的主要來源,還不知道會不會爆炸。
備份下來的東西先留著別刪掉吧...

磁碟的反應速度快很多,也許是因為 nb 的硬碟本來就比較慢,配上相對快的 cpu,壓起來剛剛好!
如果你的 gentoo 是作 cpu intensive 的工作,就別搞這個了!
