Environmental variables are not expanded in Microsoft-Windows-PnpCusto

[tundra123]

I am using an Autounattend.xml format for both W2K8 R2 and W2K8 SP2. I keep my drivers on a USB stick and use %confisetroot% variable to make the Windows installation read the drivers from USB drive. I install all boot critical drivers in WindowsPE phase and non boot critical drivers in offlineServicing pass.

<settings pass="offlineServicing">

<component language="neutral" name="Microsoft-Windows-PnpCustomizationsNonWinPE" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" versionScope="nonSxS">

<DriverPaths>

<PathAndCredentials wcm:action="add" wcm:keyValue="1">

<Path>%configsetroot%\Windows\2008\Drivers1</Path>

</PathAndCredentials>

<PathAndCredentials wcm:action="add" wcm:keyValue="2">

<Path>%configsetroot%\Windows\2008\Drivers2</Path>

</PathAndCredentials>

</DriverPaths>

</component>

</settings>

I set configsetroot to true in WindowsPE pass. Above xml works fine for 2008 R2 and 2008 R2 SP1. %configsetroot% variable is expanded and used fine. I can see the expanded path in the log files.

For some reason, this does not work in W2K8 SP2. I tried replacing %configsetroot% with %systemroot%\configsetroot. Didn't work. But if I modify %configsetroot% with "D:\", it works. So it is not able to handle environment variables. I do not want to use hard-coded path if possible, as the driver letter might change based on system.

Any suggestions/comments?

Thanks in advance.

What about using that component in the AuditSystem pass?
