I think this would be an awesome talk. I'm particularly interested in
the /sysroot upgrading process.
I like the idea of having an immutable root that you can unwind
things if they go horribly wrong.
I'm game for having this as our Dec. topic!

I'd just like to say I had a fun time at Thursday's meeting! I'm
already looking forward to the next meeting as I'm sure there are
plenty of interesting topics we could discuss.
As mentioned before, I think we could examine technologies that'd
beneficial to Linux on the desktop, like comparing packaging
technologies including Flatpak, Snap, and AppImage.
I think we could also look into the future of containers on the
as a whole with projects like Flatpak, toolbox, podman, and
My workflow over the past few years has been using these upcoming
technologies as daily drivers as they lead to saner development.
example, my laptop runs Silverblue (
) which is a Fedora
variant designed around immutability where a new system image is
committed as the new /sysroot without affecting the state of the
running system. This is reminiscent of Android A/B updates,
the update backend -- ostree -- has elements of a version control
system like git.
also interesting as it lets you switch into an unprivileged
environment that can be built up and torn down without affecting
host as tools are installed inside a container. For example, I can
build and install duc inside a toolbox without actually installing
the host /usr:
[jstone@jstone-laptop ~]$ toolbox create --release 31 --container
[jstone@jstone-laptop ~]$ toolbox enter --container duc-test
⬢[jstone@toolbox ~]$ git clone https://github.com/zevv/duc
⬢[jstone@toolbox ~]$ cd duc
⬢[jstone@toolbox duc]$ sudo dnf --assumeyes install gcc make
automake pango-devel cairo-devel tokyocabinet-devel ncurses-devel
⬢[jstone@toolbox duc]$ autoreconf --install
⬢[jstone@toolbox duc]$ ./configure
⬢[jstone@toolbox duc]$ make
⬢[jstone@toolbox duc]$ sudo make install # no password needed
⬢[jstone@toolbox duc]$ mkdir ~/.cache/duc
⬢[jstone@toolbox duc]$ tcbmgr create ~/.cache/duc/duc.db
⬢[jstone@toolbox duc]$ duc index ~
⬢[jstone@toolbox duc]$ duc gui
Finally, I've been installing most of my apps as Flatpaks, which
the same file storage backend as Silverblue to manage apps and
runtimes. This app distribution technology allows you to decouple
and operating systems as everything is built and run inside a
making upgrades easier. Compare needing only one version of an app
package as a flatpak, versus packaging for different versions of
I'd be glad to hear what everyone has to say!
