Basically, this is not similar. If you are a slave for the root zone, you not 
only cache the root nameservers itself, but also the nameservers used for the 
resolution of first-level subdomains. If you are a stub, you basically get 
nothing besides a hint-zone; otherwise you'd have to configure a stub-zone 
for every TLD that's out there (and configured in the roots) with the 
respective info to actually achieve (permanent) caching of TLD-NS-records in 
the form of a zone-file.
