1. I expected there's a pre-installed GUI utility in Ubuntu to change hostname.
我期待 Ubuntu 中存在一個預先安裝的用來修改 hostname 的圖形介面工具。
2. I expected it appears in GNOME Control Center(a.k.a. System Settings) -> Details -> "Device name" textbox
我期待這個工具會出現於 GNOME 控制中心（也就是「系統設定值」）→詳細資料→「裝置名稱」文字編輯方塊中
* In fact there's really a "textbox" at the location but is not editable and there's no "Unlock" button at that view.
事實上在那個位置真的有一個「文字編輯方塊」但是它不能編輯且於那個視野中沒有「解除鎖定」按鈕可以解鎖它
3. I expected if I run GNOME Control Center as root (gksudo gnome-control-center) I can change my hostname
我期待如果我以 root 的身份執行 GNOME 控制中心(gksudo gnome-control-center)我可以變更我的 hostname
* In fact when GNOME Control Center run as root, the "textbox" really turn's into editable, but edit the content still won't apply to the system temporarily nor permanently.
* 事實上當 GNOME 控制中心以 root 的身份執行時，那個「文字編輯方塊」真的變成可以編輯的樣子，但是編輯其內容依舊不會暫時或永久地套用到系統中。
4. I supposed there's many user having the same conclusion like me, so please help ;)
我假定有許多使用者跟我一樣有相同的結論，所以請幫幫忙 ;)
