[K12OSN] Stale packages after ugprade

[Michael Blinn]

  After upgrading from v5->v6 using ISOs last week, I have these 
packages still around. I'm assuming they're needed, but I'm wondering 
why they weren't upgraded? Were they replaced by other packages, or is 
this just a quick of naming/versioning?
Thanks,
 Michael
