[Condor-users] VirtualMemory attribute under Linux 2.6 kernel

Hi -

I know that under the Linux 2.6 kernel, the Condor 6.6 series will set the VirtualMemory and TotalVirtualMemory ClassAd attributes to 0 (presumably because of the change to the relevant bit of the /proc filesystem under 2.6). I have two questions about this:

1) Does this matter? i.e. does Condor care about this, or will anything
   not work properly because of this?  I assume that if users submit jobs
   which have either of these attributes in their Requirements then those
   jobs won't get matched to machines with the 2.6 kernel (unless the
   Requirement was that the attribute was 0!).

2) Is there any way I can override this setting, say by setting something
   in the condor_config file (like I can do with MEMORY= for the Memory
   ClassAd attribute) or in the Condor daemons' environment?
