That doesn't make sense to me. Wouldn't more things break if you only updated them every six months and had to retest the whole system rather than the parts that changed as you went along. I found that upgrading Ubuntu/Debian to the next release always screwed everything up as basically all the packages changed. Heck fedora couldn't even update to the next release until fed up came out.
