重装系统

换了一块硬盘，重装一下系统。以前配好的系统，可惜又要重新折腾了。

有两个地方需要记一下。

1. 安装myeclipse的时候，系统提示 MOZILLA_FILE_HOME not set，原因是系统缺少内置的浏览器，debian系统需要装libxul0d包
启动tomcat会提示失败，这个需要将tomcat目录的属主设成用户，其他办法没有试过，应该还有办法

2. 硬盘大了，装一个virtualbox玩玩，发现不能以普通用户身份启动，尽管将用户加入了vboxusers组，系统还是会提示：
WARNING: You are not a member of the “vboxusers” group. Please add yourself to this group before starting VirtualBox.
怒了，给用户sudo权限，这下就ok了
