I tried that. In fact, I tried setting up an apt.conf file with the
following contents:

  APT { Clean-Installed "true"; }


I launched augtool, the file was parsed fine. I changed the value to
"false", triggered "save" and it failed with the "malformed node"
error. So it was fine the get way, but not the put way, for the very
same syntax.
