Good question. That script may have options to undo some of this; generally,
this kind of minimization isn't so interesting for "pets", and some aspects
(lack of man pages!) are probably actively unwanted.

Also, I know you know this but just as a general clarification: the cloud
image isn't currently using NetworkManager anyway but is using the good ol'
network initscripts.
