This is only partly true, removing edubuntu-desktop in most cases won't 
remove the packages it installed as dependency unless you run "apt-get 
autoremove" or similar later on. Then all the packages edubuntu-desktop 
depends on and that haven't been explicitly marked as manually installed 
will be removed.

Also, once you remove edubuntu-desktop upgrades to another version of 
Edubuntu will either fail or be partial (as edubuntu-desktop is what we 
use to push new packages on your system).

The cleanest solution to the problem is to install the ldm package from 
the daily PPA and ONLY the ldm package. Downloading the .deb and 
installing manually in the chroot will do that just fine.
