Examples of matrix columns (assuming the rows lists the repos): paid professional or volunteer maintained? (E.g., Fermilab/CERN has paid professional staff assigned to SL) Timeliness of updates (e.g., only TUV based, or fixes/extensions before TUV)? Strict separation of production RPMs from beta RPMs? Particular emphases? A matrix or a similar data structure would save all of the time digging through a threaded discussion. Yasha Karant

Examples of matrix columns (assuming the rows lists the repos): paid professional or volunteer maintained? You answered your own question right here. What paid professional is paid to maintain such a list? And if it matters to you that a repo is maintained by a paid staff, then you'd probably also not trust a list maintained by voltunteers (Who would validate the list to standard? And what employer sets the standard?). So if you yourself decided to create such a list it would be in your spare time as a volunteer effort, thereby invalidating its use by others who want such a list and only trust work performed by paid staff for said purpose. Etc. This is a circular line of questioning which crops up from time to time; the answer remains the same.

Etc. This is a circular line of questioning which crops up from time to time; the answer remains the same. I am not attempting to start an off-topic discussion. The answer to the question is pertinent to practical use of the distro. This is not circular reasoning. Both the SL (Fermilab/CERN) and PUIAS (Princeton University and the Institute for Advanced Study) EL distributions/repos are maintained by a paid professional staff -- albeit lightly maintained compared to the resources expended by TUV or other for-profit corporations. Although the maintainers may have additional duties assigned to them by their employers, both distros have paid professionals directly involved as part of their immediate and continuing duties. In the case of a more typical university such as my own institution, we mostly have relatively short term GSRAs doing this work with some assistance from advanced undergraduate students, supervised by tenure-line Faculty members who have many other responsibilities (including getting the external funding to support research, as well as producing papers, funding proposals, conference presentations, university shared governance, and a host of other duties, such as direct classroom instruction). However, having a paid professional staff, with professional expertise, typically produces a more robust product (unless for-profit management personnel dictate otherwise) and allows software to be maintained. Back to my question: is there such a matrix? Has anyone -- paid professional or volunteer -- prepared such a matrix? Or must one dig through numerous listserve threads to garner the information, essentially anew for each person doing the digging? Yasha Karant

Moreover, there is no discussion of the relative quality or reliability of these various repos; e.g., is the practical definition/criteria between production and pre-production (beta or earlier) RPMs the same on each of these repos?

This was just to make it easy to find 6 . and a repo named '6rolling': ftp://ftp.scientificlinux.org/**linux/scientific/6rolling/ftp://ftp.scientificlinux.org/linux/scientific/6rolling/ My questions: - What are the differences between these different kinds of repos? - When should I be tracking the '6' repository vs the 6.2 repository vs. the '6rolling' repository? 6x is a symbolic link that points to the current release of 6. This is so you always find the current release. We also provide a yum-conf which which points to 6x. When a new point release is made all the systems with their yum-confs pointing to 6x will be updated to this newer version. Note the non yum-conf 6x will keep the system at that point release. I am mostly interested in security updates, and am less interested in feature updates. Will the 6.N repositories (6.1, 6.2, etc) continue to receive security updates for several years, or should I consider upgrading to the next point release (From 6.1 to 6.2, for example) in order to continue receiving security updates? We will update the faq. This is a very good question for it.
