Why we decided for and against Ubuntu Core

I work in a different industry and am responsible for maintaining a fleet of bare metal OSes (we currently use Ubuntu).<p>Bare metal management really feels like an unsolved problem. Whilst everybody working with cloud environments is whisked away by the latest shiny tools like Docker and Ansible, those of us working with bare metal are still trying to find a way to keep machines up and running with an OS that doesn&#x27;t get corrupted from unexpected poweroffs or permanently cut itself off from the network because of a bad config.<p>The only existing candidate I&#x27;ve seen is Balena, but it only supports specific hardware and the cost is probably so high that we wouldn&#x27;t be making a profit if we went with it.<p>At my current employer we are building a custom flavor of Ubuntu and provision it with Puppet, but we still get failures, and it&#x27;s far from the immutable haven that DevOps guys would be used to.

I got mixed feelings after reading this.<p>Do they want all the &quot;features&quot; for free, I went to <a href="https:&#x2F;&#x2F;ubuntu.com&#x2F;core" rel="nofollow">https:&#x2F;&#x2F;ubuntu.com&#x2F;core</a> and it says 10 year security update commitment, it doesn&#x27;t say it&#x27;s going to be free, how Canonical will make money?

Ubuntu is losing its shine as years go on.<p>It once was a Debian that just worked, nowadays is some kind of a trap. As you start getting deeper you start to notice non-standard things that get in the way more than they should, besides being utterly non-standard.<p>Things i noticed so far:<p>- auto-update enabled by default. if I boot a vm it&#x27;s going to be nearly unusable (can&#x27;t install packages) because it&#x27;s going to spend the first 30 minutes doing a full upgrade<p>- netplan -- not sure why that&#x27;s there<p>- snaps. for everything. the last straw for me was realizing that gnome-calculator packaged as a snap. it took almost 20 seconds to show the f-ing calculator. every time an app is slow i suspect that&#x27;s because it&#x27;s packaged as a snap.<p>- doing weird stuff with motd. why?<p>At this point my next reinstall will be a good old Debian.

I once spoke with a Canonical Sales guy and he asked me why i said that snaps were not good in the conversation we had prior.<p>Somehow nobody at canonical thinks that snap performance is an issue at all, he was genuinely surprised. Snap is just unusable, full stop. If everything takes like 10x to open i can not work with my system anymore. I&#x27;d rather work with windows or a chalkboard instead.

I would have loved to see a comparison of Ubuntu Core against openSUSE MicroOS (<a href="https:&#x2F;&#x2F;en.opensuse.org&#x2F;Portal:MicroOS" rel="nofollow">https:&#x2F;&#x2F;en.opensuse.org&#x2F;Portal:MicroOS</a>), I wonder whether it would be up for the task they had in mind.<p>&quot;In other words openSUSE MicroOS is an operating system you don&#x27;t have to worry about. It&#x27;s designed for but not limited to container hosts and edge devices.<p>...<p>- Read-only root filesystem to avoid accidental modifications of the OS<p>- Transactional Updates leveraging btrfs snapshots to apply updates without interfering with the running system<p>- health-checker to verify the OS is operational after updates. Automatically rolls back in case of trouble.<p>...&quot;

If I were them, I&#x27;d go with something that provides an immutable root FS (or at least immutable &#x2F;usr) and atomic whole-system updates, the way Chromium OS and Flatcar Linux (former CoreOS) do. IIRC, Balena does this for the base system, but adds containers on top.

Canonical&#x27;s engineers are very talented. And Canonical provides some truly innovative solutions (MaaS and JuJu come to mind. Snaps to a lesser extent). However, as anecdotes like these show, their user&#x2F;customer hostile attitude makes one very hesitant to adopt their tech.

&gt; Nevertheless, we were able to build a comparably lean system with Debian: The base systems of both Ubuntu Core and Debian each have a total size of about 1 GB.<p>This line made me somewhat sad. But it is possible that I am just being old and grumpy.

Once again, NixOS would be an amazing solution in this scenario.

It seems that Ubuntu&#x27;s 10 years support (ESM, provided by Ubuntu Advantage program) is $225&#x2F;y for a server. I can&#x27;t find price for Core, but I expect the same or cheaper. IMO it&#x27;s fair price to maintain ancient distribution. For Desktop is $25&#x2F;y, cheap!<p><a href="https:&#x2F;&#x2F;ubuntu.com&#x2F;advantage&#x2F;subscribe" rel="nofollow">https:&#x2F;&#x2F;ubuntu.com&#x2F;advantage&#x2F;subscribe</a>

Don&#x27;t get me wrong but I don&#x27;t really understand why for server stuff do you could prefer Ubuntu in favor of a rock-solid operating system like Debian?<p>One number, Debian Buster for example is LTS until June 2024 + 2 yrs. Just to mention one strength, I don&#x27;t tell you about the well-known ones such as large community, fully openness, among others.

They raise some good points. However I think it is absurd to expect a company to be blamed for having a feature wall for paid features. You’re trying to use a paid feature for free, that’s uncool.<p>I see the point about long term support being deceptive, and also the mixed messaging being confusing.

The extended LTS offering by Freexian for Debian is a paid service, although cheaper than the Canonical Brand Store price:<p><a href="https:&#x2F;&#x2F;wiki.debian.org&#x2F;LTS&#x2F;Extended" rel="nofollow">https:&#x2F;&#x2F;wiki.debian.org&#x2F;LTS&#x2F;Extended</a>

hardware wise. use a bsd. FreeBSD. there are reasons why hardware vendors are almost 100% BSD based.<p>Its rock solid and you can depend on it being engineered well.<p>Snaps , docker, and various other solutions are symptoms of a problem not a solution. The problem is userland is in a complete mess in linux. Fix the kernel and userland together, and everything flows.

Seems like there&#x27;s room for a vendor that takes something like Firecracker or Gvisor and tailors it for embedded devices.
