First, given the changes you have made to users' groups, I would make
sure to include the group in the chown directives:

chown -R ldm:users *

Yup.

I don't think you have to reinstall, but...

I don't know.

Back to the question of how /home became owned by a user other than
'root'. I believe that this was the cause of all of the problems.

Now I understand.

Oh, I meant if one were to foolishly do that in the /var or other 
"important" subdirectory.

Ok. Well, I think everything is fixed now, and weather3 is now ingesting 
data from the Internet instead of weather2. And weather2 is feeding 
(mostly) off of weather3.
