Exploring Linux containers

They're not quite virtual systems, since they rely on the host OS to operate, nor are they simply applications. Dan Walsh from Red Hat has said that on Linux, "everything is a container," reminding me of the days when people claimed that everything on Unix was a file. But the vision has less to do with the guts of the OS and more to do with explaining how containers work and how they are different than virtual systems in some very interesting and important ways.

  • A Modularity rethink for Fedora

    We have covered the Fedora Modularity initiative a time or two over the years but, just as the modular "product" started rolling out, Fedora went back to the drawing board. There were a number of fundamental problems with Modularity as it was to be delivered in the Fedora 27 server edition, so a classic version of the distribution was released instead. But Modularity is far from dead; there is a new plan afoot to deliver it for Fedora 28, which is due in May.

    The problem that Modularity seeks to solve is that different users of the distribution have differing needs for stability versus tracking the bleeding edge. The pain is most often felt in the fast-moving web development world, where frameworks and applications move far more quickly than Fedora as a whole can—even if it could, moving that quickly would be problematic for other types of users. So Modularity was meant to be a way for Fedora users to pick and choose which "modules" (a cohesive set of packages supporting a particular version of, say, Node.js, Django, a web server, or a database management system) are included in their tailored instance of Fedora. The Tumbleweed snapshots feature of the openSUSE rolling distribution is targeted at solving much the same problem.

    Modularity would also facilitate installing multiple different versions of modules so that different applications could each use the versions of the web framework, database, and web server that the application supports. It is, in some ways, an attempt to give users the best of both worlds: the stability of a Fedora release with the availability of modules of older and newer packages, some of which would be supported beyond the typical 13-month lifecycle of a Fedora release. The trick is in how to get there.

  • We Didn't Pull CPU Microcode Update to Pass the Buck
  • Red Hat Will Revert Spectre Patches After Receiving Reports of Boot Issues

    Red Hat is releasing updates that are reverting previous patches for the Spectre vulnerability (Variant 2, aka CVE-2017-5715) after customers complained that some systems were failing to boot.

    "Red Hat is no longer providing microcode to address Spectre, variant 2, due to instabilities introduced that are causing customer systems to not boot," the company said yesterday.

    "The latest microcode_ctl and linux-firmware packages are reverting these unstable microprocessor firmware changes to versions that were known to be stable and well tested, released prior to the Spectre/Meltdown embargo lift date on Jan 3rd," Red Had added.

CentOS Linux 7 and 6 Users Receive New Microcode Updates for Intel and AMD CPUs

Filed under
Red Hat

CentOS Linux is an open-source, free, enterprise-class, and community-supported operating system based on and compatible with Red Hat Enterprise Linux. As such, it regularly receives new important security updates as soon as they are released upstream by Red Hat.

About two weeks ago, CentOS Linux 7 and 6 users received kernel and microcode updates that mitigated the Meltdown and Spectre security vulnerabilities unearthed earlier this month. However, after some thorough testing, Red Hat discovered that these updated microcode firmware developed by Intel and AMD caused hardware issues.

Fedora Makes Progress On Their New Modularity Concept

Filed under
Red Hat

After abandoning their Fedora Server 27 Modular Edition work last year, Fedora developers interested in modularizing Fedora packaging have drawn up new plans that are now approved by the Fedora Council.

At Wednesday's Fedora Council meeting, the new Fedora modularization plan was approved. The goal outlined by "Objective: Fedora Modularization — The Release" is "Modularity will transform the all-in-one Fedora OS into an operating system plus a module repository, which will contain a wide selection of software easily maintained by packagers. This iteration of the Objective focuses on the second part — providing a wide selection software in various versions — while laying the groundwork for the first."

The new Fedora Modular plans no longer involve modularizing the entire distribution but rather "traditionally built packages" will remain and only components benefiting from modular features would be modularized. The components targeted are things like database servers, web servers, Node.js, etc, where users may prefer sticking to one particular version of a program and not upgrade until it's end-of-life or has other particular reasons to want to move on to a newer version.
