Ubuntu Linux的最新版本，代号为Hardy Heron的Ubuntu 8.04 LTS即将发布，现在Ubuntu FANS门最关心的话题之一最多的就是：是在现有Ubuntu的基础上升级还是重新再安装系统呢？
Linux用户向来喜欢“分门别派”，在这个问题上就有两个阵营，有的人认为，要想完整了解新版本，体验新版本的新特性，就得从新安装一遍；另外一拨人认为，基于Debian的apt包管理系统已经非常方便了，从新安装简直就是脑子进水。
现在就让我们看看，两者这间的优缺点吧
As the release of Ubuntu 8.04 LTS rapidly approaches, the all important question is beginning to form in everyone’s mind. Upgrade, or freshly install.
It’s always an interesting discussion to have with fellow Linux users, because there seems to be an almost religious divide between the two camps. Some feel that to really get the full experience of a new version, a clean install is the only way. The other side, however, argues that the Apt package management makes upgrading so simple and complete, that it’s silly to reinstall. Let’s take a quick look some advantages and disadvantages of both sides:
Fresh Install
Pros:
* You get to see any changes added to the installation routine
* It’s a great time to change partition schemes if you want to do so
* If you have any lingering cruft from system hacks, etc -- they get sterilized
* You get that "fresh out of the shower" feeling when you log in
Cons:
* All settings and preferences are gone (assuming you wiped /home)
* All those system hacks might still be needed, and you’ll have to redo
* It takes a long time
* You get less bragging rights about how long you’ve gone without a reinstall
Upgrade
Pros:
* Very simple. 2 commands and a reboot is all it takes
* Any system modifications usually stick
* Most preferences in applications upgrade fine
* You get to brag that you haven’t reinstalled your OS in 10 years
Cons:
* If things aren’t quite working right, upgrading seldom "fixes" things
* Some non-standard system modifications no longer work
* Occasionally new features aren’t installed properly with an update (compiz?)
* You don’t have an Ubuntu CD to give away to a Windows friend when you’re done
In reality, personal preference is what determines the ideal scenario for the individual user. I personally like to reinstall the entire OS, including my /home partition. That might seem like overkill, but I really like that "fresh out of the box" feeling. Plus, I really enjoy the installation process, so for me it’s just plain fun!
If you’re an Ubuntu (or KUbuntu, or XUbuntu, etc) user, be sure to stay tuned later this month for the release of Hardy Heron!
