SharePoint 2010 & .NET 4

Our backup admin needs to install Avamar SQL Agent on the SharePoint 2010 server and Avamar needs .NET 4 to be installed, so is it going to cause any problem?

We already know that SharePoint 2010 works only with .NET 3.5 and it doesn't support .NET for in application developments. but what about having both .NET 3.5 and .NET 4 installed on the SP server, I've been searching and here is what I found:

Here is a link to Technet where someone asked the same question, people argue both cases where it is OK to have both .NET versions and also some say, it may cause problems.

as an example, if you want to install the June 2011 patch, here is a key known issue on the description:

 Known issue 1
If you install an earlier build of this hotfix package on a SharePoint server that has the .NET Framework 4 installed, you cannot synchronize user profiles from Active Directory and LDAP into the SharePoint User Profile Service application database. The user profile synchronization export process fails. Additionally, the System.PlatformNotSupportedException exception shows in Event Viewer.
Note This issue is fixed in build 14.0.6106.5002 of this hotfix package.

From my experience, If you don't need to add any hotfix or major change on the server, then installing .NET 4.0 is fine, so if you are building a new server then leave it for last.
