eu-os.gitlab.io received a few updates today after some legit criticism.

- Logo has now consistently a purple gradient for more distinction to EU flag 🇪🇺.
- Home page: EU OS is not yet an EU project
- FAQs acknowledge that Linux is already used in the public sector. The unique selling point is better clarified: use of #bootc and more collaboration across the EU to bring down the costs for a migration from Windows #endof10
- university of Oslo added to use cases 🎉

Sorry #OpenSUSE but BTRFS snapshots don't offer the same functionalities of #Bootc or RPM-OSTree+OCI images that would be perfect for multiple vendors like public institutions looking for "layering" their customizations on top of each others.

@zygoon Thanks! These seem nice for testing any OS workload. #bootc is a bit special as the result/artifact *is* the OS image, so the very point is to *not* use a "standard" OS image. But this is of course useful for testing just about any other project on the common distros.

The Universal Blue team was tired of waiting for upstream so we did it ourselves and made a Live ISO builder for `bootc` images: Titanoboa! It's currently in a pretty alpha-ish state since we've started developing this like 3 days ago, but its already somewhat functional and Blue95 (a custom windows95-like image made by Adam Ledif) already has a functioning live installer for the image if you wanna try it out!

What does this mean for you? Faster, smaller, and more accessible installation environments :)

Bootc as a project is one with tons of promise and lots of community support. It's what is powering the next generation of Atomic Desktops, CoreOS, and Fedora IoT, not to mention all of the work that @UniversalBlue has done to show off everything that can be done today.

If you want to follow bootc more closely, regular updates from Fedora's end are shared here. :)

@jschreuder @eu_os

To my knowledge #opensuse is not yet available as images with rpm-ostree layer. Though I think this development and #bootc are big advantage for organisations who already work with containers. It is also an advantage for organisations that would require more than one image for different ministries/departments/user groups.

I have followed the development on #MicroOS and @kalpa . It was still beta last time I checked. It works differently.

One thing I have from immutable (atomic) distros, and is how cumbersome is installing apps that require root permissions.

Supposedly you have to use Distrobox. Even that never worked for me. I always have to resort to `rpm-ostree` and then uninstall it so BootC can update the system. Every single time.

#Linux#Distrobox#OCI

NixOS is cool, but it's nothing new. I've seen many smart people doing an excellent job with chroot, symlinks, and Chef/Puppet long before NixOS came along. A really cool thing is the Atomic desktop and bootc model. If you want a secure and solid environment, the Atomic desktop is the way to go. There's a learning curve, but it opens up a whole new world for you. #nixos #atomicdesktop #bootc

So altfiles provides the value, but `systemd-sysusers` will not create the group in `/etc/`, and `usermod` only operates properly on `/etc` as the filesystem at `/usr` is read-only. It should create the entries in `/etc/` instead or error.

Doing
```
$ sudo bootc usr-overlay
$ sudo rm -f /usr/lib/group
$ sudo systemd-sysusers
```
is possible, but this feels like a worse workaround than:

```
$ echo "users:x:100:gbraad" | sudo tee- a /etc/group
```

Continued thread

It is related to systemd-sysusers.

On a regular #Fedora system I see:

```
$ sudo systemd-sysusers --dry-run --inline "g users 100"
Creating group 'users' with GID 100.
Would write /etc/group…
Would write /etc/gshadow…
```

but on a #bootc system it returns nothing.

```
$ sudo systemd-sysusers --dry-run --inline "g users 100"
$ cat /etc/group | grep users
$ sudo cat /etc/gshadow | grep users
$ getent group users
users:x:100:
```

My instant Developer Environments
- github.com/gbraad-devenv/

Automated the container image builds, and therefore updated them all. This includes disk images for VMs using #bootc

These are based on my personal dotfiles
- github.com/gbraad-dotfiles/

Some of the scripts I have allows to easily spin up these containers:

$ devenv fedora [start|shell|root|...]

and as virtual machine with #bootc:

$ machine fedora [download|create|start|console|...]
