Say Hi To Microsoft's Own Linux: CBL-Mariner (zdnet.com) 110

Posted by BeauHD from the who-are-you-and-what-have-you-done-with-Microsoft dept.
An anonymous reader quotes a report from ZDNet, written by Steven J. Vaughan-Nichols: Microsoft now has its very own, honest-to-goodness general-purpose Linux distribution: Common Base Linux, (CBL)-Mariner. And, just like any Linux distro, you can download it and run it yourself. Microsoft didn't make a big fuss about releasing CBL-Mariner. It quietly released the code on GitHub and anyone can use it. Indeed, Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide on how to build an ISO CBL-Mariner image. Before this, if you were a Linux expert, with a spot of work you could run it, but now, thanks to Rey, anyone with a bit of Linux skill can do it.

CBL-Mariner is not a Linux desktop. Like Azure Sphere, Microsoft's first specialized Linux distro, which is used for securing edge computing services, it's a server-side Linux. This Microsoft-branded Linux is an internal Linux distribution. It's meant for Microsoft's cloud infrastructure and edge products and services. Its main job is to provide a consistent Linux platform for these devices and services. Just like Fedora is to Red Hat, it keeps Microsoft on Linux's cutting edge. CBL-Mariner is built around the idea that you only need a small common core set of packages to address the needs of cloud and edge services. If you need more, CBL-Mariner also makes it easy to layer on additional packages on top of its common core. Once that's done, its simple build system easily enables you to create RPM packages from SPEC and source files. Or, you can also use it to create ISOs or Virtual hard disk (VHD) images.

As you'd expect the basic CBL-Mariner is a very lightweight Linux. You can use it as a container or a container host. With its limited size also comes a minimal attack surface. This also makes it easy to deploy security patches to it via RPM. Its designers make a particular point of delivering the latest security patches and fixes to its users. For more about its security features see CBL-Mariner's GitHub security features list. Like any other Linux distro, CBL-Mariner is built on the shoulders of giants. Microsoft credits VMware's Photon OS Project, a secure Linux, The Fedora Project, Linux from Scratch -- a guide to building Linux from source, the OpenMamba distro, and, yes, even GNU and the Free Software Foundation (FSF). To try it for yourself, you'll build it on Ubuntu 18.04. Frankly, I'd be surprised if you couldn't build it on any Ubuntu Linux distro from 18.04 on up. I did it on my Ubuntu 20.04.2 desktop. You'll also need the latest version of the Go language and Docker.

          They realize that orgs will still need/want to run Linux for *something* and so they were making changes needed for it to run on Azure.

          And their own distro is the obvious next step.

      • This has nothing to do with taking over Linux, from the linked-to article:

          If I had a dollar for every time an "internal" tool ended up as a product I'd be a millionaire.

          The bottom line is that if it's good enough for them to use in their infrastructure, it's good enough to turn into product and another revenue source. You'll see.

It wouldn't be the only Linux I'd run, in part because I have machines where I have no need to run Windows applications, and in part because I only trust Microsoft so far. But I have a sizeable library of Windows software (mostly games, surprise!) and I'd like to have some plan as to how to run

Microsoft is not going to give up the rights to the sources any time soon. So I could see them porting NTVDM et al to Linux, but I can't seem them giving Wine what it needs for "full" compatibility. (The quotes are because Windows doesn't have perfect backwards compatibility either, though it is admittedly very good.)

      Right. Their sharing an internal tool developed to support Azure is step one of their plan to what - sell it commercially?

      There's little Microsoft could do to make it harder to install - they don't offer an ISO image, the base install is minimalist to the point SSH isn't included, there's no 'desktop' and by default almost nothing is installed.

      Snd let's not forget the absolute lack of any announcement, release, or offers of available support - they simply shared out their code on GitHub and a couple MS employees shared blog posts about it. Wow. That's some stealth marketing designed to take over the Linux market!

    This actually makes perfect sense in tandem with their release of Windows 365. Having a very small and secure kernel on a PC that is then used to "stream" a Windows 365 cloud-based desktop environment would be a big winner for them. They could hike up the price for OEM installations of Windows 11 and offer "free" 6 month subscriptions for new PCs. Then people would have to pay a subscription to Microsoft to keep using their own computer.

    • I feel like that's not the use case for the cloud desktop. The cloud desktop would be to replace the necessity for 3rd party VPN tools and remote desktop. MS always makes their changes around the corporate environment. Other than the Xbox, all of their consumer oriented shit fails. Build it for corporate, then market it to the public

      • Yeah, I realize the short game is Enterprise but like you said, eventually they make Enterprise features to the public. In this case, I think it strengthens their push to getting folks accustomed to paying a subscription for everything they do on or with a computer.

    • This offering has no 'desktop' - its a server appliance distro, nothing more - and this hasn't been 'released' it's being shared, most likely to simplify compliance with GPL requirements.

    • This software has nothing to do with Windows 365 announcement - at all:

      The goal of Mariner is to be used as an internal Linux distribution for Microsoftâ(TM)s engineering teams to build cloud infrastructure and edge products and services.

    • Then people would have to pay a subscription to Microsoft to keep using their own computer.

      *sigh*. Repeat after me: Windows 365 is *NOT* a desktop OS for the home PC. It has use cases no different to what any Azure customer has today and the only thing new it brings to the table is being able to run without RDP.

      Office 365 also doesn't "stream" from the internet, and locking a system down with subscription has nothing at all to do with where the OS is installed or which hardware it is running on.

      These conspiracy theories are tired because they just don't make sense.

      Every day Linux is, slowly but surely, getting closer to world domination.

      Linux already dominates the world. Very little doesn't run it at this point. It's so dominant that MS had to start including it in their OS as they were losing developer market share from lacking it. About the only place it hasn't taken over (yet) are desktops and laptops.

      • Except desktops/laptops. Linux has the server market, and the 'shit that fits in your pocket' market, but not desktops or laptops, not even if you count Chromebooks.

        Did you actually read the article? This is a minor distribution that MS created to use internally to support Azure infrastructure. They likely posted it on GitHub to comply with GPL requirements.

          With a four digit uid, you should know it's tradition to not read the article ;-)

        • But the GPL doesn't require them to run/maintain RPM repos with binaries, generate documentation and install instructions, etc. This is more than "the legal department says we have to do this". I have a feeling if that were the case then you'd need to send a letter to them and they'd mail back the minimal source needed to comply on a CD.

    I thought so.

    Basically, the vast majority of you are just talking out of their ass, because it's "kewl" to bash Microsoft of Slashdot. Tribalism.

    Personnaly, I'm going to download, build, and try CBL-mariner, because I like to try new distros, because it seems to be strongly inspired by Fedora (which I like very much), because I can, and, incidentally, because it will piss off a whole bunch of people here.

    • The distro may be perfectly fine! That should not confer sainthood on Redmond. One thing is not the other.

    • Don't bother - it doesn't build cleanly - "Have you hydrated the filesystem" - error is in their issue tracker. Could do with better quality control

      I thought so.

      This isn't about tribalism this is about MS doing what MS wants to improve its market position how it thinks that may be perceived.

      To me all their efforts so far seem self-centred and not at all for community good in the sense that Open Source and open standards thrives. If MS worked to make their office formats less binary blob and worked with Libre Office to assist with compatibility then I think we could say

    ...Or at least questionable. Microsoft is a monoculture and -- as long as it remains such -- will ALWAYS be the preferred target, by far, for ransomware and other exploits, at least on the desktop. How does it benefit LInux for Windows to now come commingled with a Linux attack surface? There has been a lot of celebration of Microsoft adopting Linux, but it is.a very uneven ("What can you do to help us sell more Windows software?") relationship. Security -- both because of Linux/Unix having a better security model, and also due to "security by obscurity" -- is one of Linux's big comparative strengths. And now it is being undercut by Windows coming with Linux inside as some sort of lapdog? This becomes a good reason to begin promoting and building up possibly BSD or - in the future - maybe https://www.redox-os.org/ [redox-os.org] Just a thought.
    • And that's how the corporates will lead you right into the trap. Don't focus on BSD because their license makes it a non-requirement to share modified source code. Same for MIT. Remember that proprietary code is harder to audit.

    • There is nothing obscure about linux. It may represent a tiny fraction of desktops/laptops, but it is common elsewhere and source is available to go looking for potential exploits to use.

    Itâ(TM)ll take years, but it will happen.

    Much like Appleâ(TM)s move from the old MacOS to the NeXT MACH kernel.
