Creating and/or using backports on Debian stable is a way to keep up-to-date while still being on stable. However, doesn't using backports destabilize stable? If not, why aren't backports simply a part of the main stable repository?

  • They may. Debian is very conservative with upgrading packages. Features often do not get included, whereas bugs get fixed. With backports you get the best of both worlds in a semi-official manner. However, yes: it may destabilize the system. So may running Ubuntu. Yet, people are running Ubuntu on servers. YMMV.

However, doesn't using backports destabilize stable?

Not if you are careful and selective. I use backports all the time (I run Debian stable) and have never had a problem.

The key is to avoid upgrading or otherwise changing core packages. This includes the basic libraries that are widely used in the system, including important C and C++ libraries (e.g. libc6 and libstdc++), the init system, the default versions of important language implementations like Perl and Python which the base system depends on, etc. I've also avoided upgrading big complicated subsystems like KDE and GNOME, because it just too messy, though it is debatable whether they are part of the base system. You don't have to use them. On the other hand, many end-user packages in Debian do depend on KDE or GNOME, or at least their associated libraries.

If you restrict yourself to leaf packages, i.e. packages that no other package depends on, you will be fine. This is usually the category that most end-user applications belong to, anyway. Occasionally, it is Ok to backport more important packages, as long as one is careful. For example, I have backported TeX Live, which a number of packages do depend on. Another approach is to install non-default versions of packages alongside the existing default versions. For example, Debian supports multiple versions of Python, so one can upgrade or even add more recent versions of Python without compromising the integrity of the system. Similarly, one can backport newer versions of GCC because Debian supports multiple versions of GCC. It is generally also Ok to upgrade software like the kernel and drivers, because these are usually only weakly tied to user space.

NOTE: To be clear, in my remarks above I'm including self-created backports, not just the ones made available officially by Debian via backports.org. For example, to my knowledge, there has never been a TeX Live backport made available via backports.org, though it is actually relatively easy to backport.

    Why hasn't a TeX Live backport been made available on backports.org?

  • @user89 well, someone has to do it. The obvious, person, Norbert, the TeX Live maintainer, so too busy, I think, and nobody else has stepped up. Norbert is an academic and handles TeX Live packaging single-handed in his spare time. It must be stressful. I imagine he is only doing it because nobody else is, and there are people depending on his package. Jan 24, 2015 at 23:56

    What about you? :) (or for that matter, me) -- can we write Norbert a scrip to do so?

    What about me? You mean, why don't I create an official backport? Dunno, I asked about backporting something on the relevant mailing list once, but nobody replied. I've never connected with the people who do backporting. I guess I might at some point. At you can tell, I'm not really motivated to do so... One issue is that it does require some level of commitment. For example, if your backport has a security issue or a significant bug, you would be expected to update it. Jan 25, 2015 at 1:32
