NFS Version 3 Support on Linux

Platform: Linux
TeamSite Version: 6.7.1
Content Store: Located on a NFS Share mounted on version 2
I was involved in a project where the UNIX team said they do not support nfs version 2.  This was seen as a major problem as on an Interwoven article it clearly states only nfs version 2 is fully supported by Interwoven.
After speaking with Interwoven Support and Engineering, they confirmed NFS version 3 is supported on Linux
