Wisdom of mixing stable + unstable/testing?

["Charles Thornhill-Cole" <charles@bigbridge.com.au>]

Hi,

 

If one were to install the libc6 package from unstable on top of a stable install, would it break things? how badly?

 

There are a couple of packages from unstable and testing that I would like to use on a production server running stable. Should I just compile them and play it safe?

 

Thanks,

Charles
