moving SPFiles, registry edit necessary for ServicePackCachePath?

I recently moved my ServicePackFiles Folder to a larger hard drive to free up
space on my smaller, original hard drive, the C drive. I followed the
directions of MS knowledge base articles below and updated the registry for
ServicePackFilesSourcePath as described. My registry also lists a
ServicePackCachePath, which seems to point to that same old ServicePackFiles
Folder which has now been moved. Do I need to update this path also to the
new F:\WINNT\ServicePackFiles folder?
