Re: [Condor-users] DAGMAN, 7.4.0, and NFS

[Craig Struble <craig.struble@xxxxxxxxxxxxx>]

I changed the generic configuration file to the one included in 7.4.0,  
but my pool specific configurations were unchanged (except for  
HOSTALLOW_WRITE -> ALLOW_WRITE).

I don't see any relevant references to NFS in the generic  
configuration file. Did a default value change somewhere?
