Brian, I tried to run your remount commands.  I tried first to run them
individually.  And then I tried to run them all in a block.  Each time, the
server sits after the first command is entered, like it's waiting on
something else.  When I ran it as a block, the second and third commands
repeated themselves on the screen.  When I ran them by themselves, the first
one gave a permissions error (it is 644), so I didn't run the second.
