-====== Linux and Unix version support (draft) ======
+====== Linux and Unix version support ======
-Comments are welcome on the support strategy outlined below.
 ===== Linux =====
-We support the following Linux versions
+We support Scientific Linux, which is an RHEL derivative similar to CentOS.
+  * **CentOS 7**
+  * CentOS7 will replace Scientific Linux 6.
+  * CentOS8 Stream may be supported in the future.
-  * **Scientific Linux 4**
+  * **Scientific Linux 6 has reached End of Life**
-    * "legacy" version, only supported where research project code demands it.
+    * this is our mainstream version for compute servers and desktop workstations
-    * i386 (32-bit) only.
+    * we only install the x64 version of SL6, not the 32-bit version.
-    * now not recommended for desktop workstations.
+    * Support runs until 11/2020
-    * some third party applications such as Adobe Flash are no longer supported for this version.
-  * **Scientific Linux 5**
+  * **Scientific Linux 5 has reached End of Life**
-    * "mainstream" version for long-term support
+    * legacy version for older applications which require it.
     * i386 and X86_64
-    * Some libraries and desktop applications (eg java plugin for firefox) may not be available on 64-bit (X86_64) installs.
+    * Some libraries and desktop applications may not be available on 64-bit (X86_64) installs
+    * Some features (for example, xfs file systems) are not available on 32-bit installs
-  * **Fedora Core 9/10**
+    * Support runs until 03/2017
-    * "cutting-edge" version
-    * probably for X86_64 only
-    * short support lifecycle and frequent updates.
-    * research code compatibility should be the end-users responsibility.
+  * **Scientific Linux 4 has reached End of Life**
+    * no longer supported as of February 2012
-===== Tru64 Unix =====
+===== FreeBSD =====
-  * **Tru64 5.1B-6**
+  * FreeBSD 9.x and 10.x, X86_64 64-bit only
-    * This is now **not supported** for most end-user applications which are available on linux. Eg Mathematica, LaTeX, email, text-editing, etc.
+    * Some departmental infrastructure runs on FreeBSD.
-      * To be more specific, we no longer support any custom software installations on these systems. We do have a collection of prebuilt software available from www.thewrittenword.com, and if a package is available from them, we will install it.
+    * Most systems are not accessible for login by non-IT staff.
-    * Provided for legacy code (for example, applications based on alpha fortran code) only.
+    * This is only listed so you can be aware some other types of system exist. For example, some department web servers run on linux and some on FreeBSD. Depending on the site, you may have code which is running on a BSD system rather than linux, and may not run in the same way.
