Debian Lenny is a great operating system. It just seems to be completely reliable- if there are any bugs, I haven't found them. However, what's also obvious from the first time you use it is that a lot of the packages it contains are old.
The next version of Debian Stable- called Squeeze- is long overdue. What's holding it up? Squeeze will be released when the release-critical bugs are squashed. I'd assumed these bugs were performance bugs in software packages in Squeeze, but now I think that many of them could be upgrade bugs that will foul up any upgrade form Lenny to Squeeze.
