Will "yum upgrade" upgrade in place only the applications/files that 
come stock with SL without touching existing partitions or systems 
configuration folders (e.g., network information, password, shadow, and 
the like)?

I was repeatedly told on both this and the CentOS list that TUV 
configuration no longer permitted this sort of operation (at one time, 
TUV provided production -- not just Fedora "beta" -- binaries, and 
during that epoch, the TUV installer had an "upgrade" option).
