MarkShuttleworth’s FAQ has the following passage in the answer to the question “What about the GCC 4.0 transition? Why did you adopt GCC 4.0?”:
“This was discussed with the Debian toolchain maintainers, who were themselves planning to adopt GCC 4 at some time (well, sort of involved the Ubuntu maintainer talking to himself, they are the same guy, …).”
Several minutes after reading the FAQ, I still find the above passage to be hilarious.
Note also Bug #1 in Ubuntu.
