Scientific-Linux：哪个版本有更长的支持日期？

我们有几台安装了 Fedora 14 的台式电脑，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 升级不是一个选项）。我们找到了 Scientific-Linux，并根据路线图我们有两个选择：

  1. 我们使用 GNOME 安装 6.1，并将其用于桌面目的，我们将在 2017 年 11 月 11 日之前进行更新——6 年多了！

  2. 我们安装“滚动发布”。

我没有使用过任何基于“滚动发布”的 Linux 发行版，所以我不知道这到底意味着什么。是否意味着如果我安装了一次，我们就不需要因为版本升级而再次重新安装？例如，Scientific-Linux 7 出来了，我不需要进行 dist-upgrade 吗？

答案1

你肯定想选择选项#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，滚动选项更有可能给您的系统带来不必要的重大更改。

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 个月对其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，其中包括针对您的特定 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。

从如何升级到最新的 SL 6.x 版本:

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，你在一件事上说得很对。 SL是“对于企业来说太棒了”。 :)
