Why the q: drive?
Overheard an interesting discussion on SoftGrid. Here's my spin on their talking points.
Q: Why is the q:\ drive needed?
A: Some applications write paths to the system in which they need a full path including the root. Given migrating to SoftGrid in IT is principally done via repackaging (via a tool called a sequencer) the repackager needs to provide the application install a reasonable facsilime of the system. With the Q drive provided by SoftGrid, the legacy application installer can then sprinkle a fully qualified path to settings locations such as the registry, ini files, and XML config files.
