Lan*_*nes 3 scientific-linux rolling-release
我们有几台安装了 Fedora 14 的台式机，但我们需要一个不需要每半年重新安装一次的 Linux 发行版（不，dist-upgrade 不是一个选项）。我们找到了 Scientific-Linux，根据路线图，我们有两个选择：
我们使用 GNOME 安装 6.1，并将其用于桌面用途，我们将在 2017 年 11 月 11 日之前进行更新——超过 6 年！
我们安装“滚动发布”。
我没有使用任何基于“滚动发布”的 Linux 发行版，所以我不知道这到底是什么意思。是不是说我安装一次就不用再因为版本升级重新安装了？比如Scientific-Linux 7出来了，我不需要做dist-upgrade？
你肯定想选择#1。从关于版本号的问题：
Q. What is a "rolling" release?
A. The "rolling" releases are our test releases. They are the equivalent to what
another vendor calls "rawhide". We call them rolling because they are always rolling
along and rarely stable.
They are not meant to be stable. They are not meant to be used in a production
environment. They are for testing purposes only. Depending on where we are in our
testing the rolling can be a beta, a release candidate, and for a short time, will
even match a current release.
The development team of Scientific Linux does not guarantee that a rolling
release will work. We want to make that clear. Although the rolling releases
might work just fine for the majority of the time, we might also just happen to be
testing some product that does something you don't want it to do.
与选项 #1 相比，滚动选项更有可能为您的系统引入重大的不需要的更改。
不管怎样，我向你保证，费米实验室和欧洲核子研究中心不会每 6 个月对他们的系统进行一次分布式升级。Scientific Linux 通过提供其安全勘误存储库来支持这一点，其中包括您特定 SL 版本的安全补丁。他们特别指出，这消除了管理员在每个版本中升级系统的要求。
Scientific Linux was designed so that an administrator can easily upgrade their
computer between minor releases.
It is not required that administrators upgrade their release, because the security
errata will be updated for all releases. But there are often features and/or
packages included in later releases that were not available with the earlier
releases.
不过，你对一件事很了解。SL是“他妈的非常适合企业”。:)
