Hi, I am giving my parents a laptop for Christmas this year that I put Lenny on and as I'm on the other side of the country, want to make sure they stay on Lenny until I am home in the future to upgrade to Squeeze after it officially becomes the Stable release. I've seen some emails about using "Lenny" instead of "stable" in the /etc/apt/sources.list to force aptitude to keep a Lenny system. Is this the official/accepted method? Currently I have the standard "stable" entries in sources.list, plus backports. Nothing fancy about the installation, stock kernel, etc.
Thank you, Mark
