Scientific-Linux：サポート日が長いバージョンは何ですか？

オプション＃1を選択したいと思います。 ~からバージョン番号に関する質問:

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. 

オプション1と比較して、ローリングオプションは、システムに不要な主要な変更を導入する可能性が高くなります。

それにもかかわらず、FermilabとCERNは6ヶ月ごとにシステムの分散アップグレードを実行しないことを保証します。 Scientific Linuxは、特定のSLバージョンのセキュリティパッチを含むセキュリティ正誤表ストアを提供することでこれをサポートします。特に、これは管理者が各リリースでシステムをアップグレードする必要がないことに注意してください。

~から最新のSL 6.xバージョンにアップグレードする方法:

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.

しかし、一つのことについてはあなたが正しいです。 SLはい「ビジネスに適しています。」 :)
