That's why I did this little dirty hack. Perhaps it would be an idea to 
repack just the 12.04 binaries which are needed for hydro in an extra 
repository. Then the risk to break something is little. Additionally, a 
sign "use it on your own risk" should be added.

But in my experience, apt can handle about every kind of abuse fairly 
well - to be honest I've done way trickier things in the past without 
any problems.

Best regards,
Michael Fritscher
