I will standby my previous statements as to anyone who thinks that live upgrading is a fire and forget process on any linux distribution. It is not..especially as the use case in question looks more and more like a median end-user usage case(with median end-users as admins) and less like a production server (with knowledgable admins at the helm making sure they do the necessary pre-upgrade prep)

Shrug, sure, there are edge cases and bugs you could run into. But everyone I know who runs debian does do live upgrades, and it works. The parent comment's "in practice" is, in practice, what you actually do. (And speaking for myself, I don't bother to read the release notes before doing so.)
Now, I don't actually know how things work out in practice for Fedora, but the upgrade page says "Version updates without using anaconda - such as the yum method described here - is unsupported and not recommended!" and "Although upgrades with yum do work, they are not explicitly tested as part of the release process by the Fedora QA and are not documented in the Fedora installation guide."
Maybe that warning is wrong, but it really makes it *sound* like running yum upgrade is something that is not recommended and that is untested. While, in contrast, apt-get on a running system *is* the tested, documented, and supported upgrade mechanism for Debian. They really try to make sure it works properly for most users.

Sounds like a smokescreen to me. All we are saying is that live upgrading a Debian system is supported, while on Fedora it is not. Not that it is flawless.

Stupid Debian-bashing (from a person who probably does not use it)
In place upgrades generally work just great and are supported on Debian. Sure they are not 100% perfect for everyone, but they have been for me.
