I think it needs to include it. Suppose someone used the same user ID,
same nickname but changed the machine from Linux to Windows. Furthermore
even a change like Linux 2.6 to Linux 2.8 could impact performance
significantly so it should be regarded as a new machine. The complexity
of dealing with the OS version #s is why Jim tabled the work for now. I
agree, its an ugly mess that NightlyTest shouldn't be involved in. But I
don't think the correct thing to do is remove OS version from the
comparison altogether. I'd rather have the current functionality than OS
not mattering at all.
