  • No, you don’t need to be worried. For example, Flatseal is a program to manage other flatpaks. This means that, by design, it needs to be able to grant flatpaks certain permissions that may expose them to system services they need to operate correctly.

    One user mentioned that these new warnings aren’t particularly helpful, because they don’t give a good explanation of what or why, and they just foster anxiety in users who just want to install an otherwise reputable flatpak.

    I don’t know anything about xournal++, but I would imagine it’s also reputably safe, and somebody else can verify for sure.















  • It’s a distro that makes all but a few system directories immutable. This means you can’t just install whatever you want in the same way you would install in a traditional Linux system.

    This comes with some benefits:

    • Malicious and buggy software can’t permanently fuck up your installation. Even root can’t edit those directories.
    • Each system update replaces only the system layer, but you can rollback to the previous one if something breaks.
    • You can rebase to other images (like going from Fedora Kinoite to UBlue Aurora) with a simple command, and you don’t need to reinstall anything or worry about backing up your /home directory.
    • Most software is installed via flatpaks or appimages, keeping a layer of separation between your system and your applications.
    • Distroboxes/Podman containers can handle a lot of additional software while keeping it safely containerized.
    • The system is generally reproducible, so the core of what you have is the core of what everybody else has.

    Some drawbacks:

    • You can’t install whatever you want however you want. There are some hard limitations on where files are allowed to go, and installing certain software that interacts with the kernel can be tricky (I’m currently trying to figure out the best way to install my VPN provider’s client).
    • There’s a definite learning curve to working with containers. It’s not always as simple as “create container, install thing.”
    • There’s a definite learning curve to retraining yourself to think in layers/containers.

    Some examples of modern immutable distros are:

    • Fedora Silverblue
    • Fedora Kinoite
    • Universal Blue Aurora
    • Universal Blue Bluefin
    • Universal Blue Bazzite
    • NixOS
    • BlendOS
