[Tomato] 在RT-N16 JFFS 上安裝 optware
作者: Aven 日期: 2011-07-22 00:19
RT-N16 刷完韌體還想玩什麼新鮮玩意? 32MB Flash 刷完 8MB 的韌體,千萬別浪費剩餘 24MB 空間,透過啟動 JFFS 功能,不必插 USB 隨身碟,馬上多出 24MB 空間可以使用。不過這空間大小有些尷尬,放不了幾個檔案,但何不拿來安裝 optware 呢? 底下就來介紹在 JFFS 空間裡安裝 optware。
開啟 JFFS 功能
刷完 Tomato 後,JFFS 功能預設是關閉的,所以必須到 路由器管理 => JFFS 裡手動開啟,並且執行 格式化/清除 功能,系統會進行格式化 JFFS 空間,如下圖。
指定 opt 路徑
optware 預設路徑已固定使用 /opt 路徑,所以當我們格式化 JFFS 空間後,必須把 /opt 指向 JFFS 路徑,這樣日後安裝 optware 套件,才會寫入 JFFS。
root@rt-n16:/# mkdir /jffs/opt
root@rt-n16:/# mount -o bind /jffs/opt /opt
設定自動掛載
在 路由器管理 => JFFS => 掛載後執行 欄位裡填入 mount -o bind /jffs/opt /opt
下次重啟時,系統會自動掛載進來。
下載安裝 optware script
這裡參考 TomatoUSB 上的教程下載 optware-install.sh

經過上面幾個步驟,RT-N16 可以很快速的建立起 optware 環境,馬上與上千種套件接軌,有機會我們再介紹 optware 套件的應用,若您迫不及待,可以前往WL-500g 系列改機文件索引參考如何安裝設定套件。
底下將 optware 安裝於 JFFS 的優缺點,做個整理:
優點:
1.無須外接 USB 隨身碟,無須分割磁區,即可快速打造 optware 環境。
2.因 JFFS 使用 Flash 記憶體,可視為小容量隨身碟,關機後資料依然存在。
缺點:
1.日後若韌體有升級後,上述流程還要重做一次。
2.JFFS 容量寸土寸金,僅適合安裝常用小巧的工具套件,請斟酌使用。
3.因 JFFS 使用 Flash 記憶體,故不建議在上面執行大量存取磁碟的套件,以免折損 Flash 記憶體使用壽命。
