外面的雪花無憂無慮地飄在這小寒的時節裏
這個週六就臘八了
天色漸漸暗了下去
噼裏啪啦的鍵盤聲鼠標聲一如往昔
不斷
我還是先加塊兒硬盤吧， 我的虛機沒空間了。
說幹就幹
開VirtualBox， 給虛機（Open SUSE Linux 10.2， 上篇博文有提到） ）加一個4G硬盤
用Putty登錄虛機
- login as: root
Authenticating with public key "rsa-key-20130110 [email protected]" from agent
# 虛擬機嘛， 就是用來糟蹋的， root 登錄， 堅決不用密碼， 可勁rm.. 因爲這個是我clone滴， 嘿嘿
