Sorry to write here, but there is an interesting moment. For a long time I was collecting live CD on Fedora (then Fedora client had a regular installer), then I saw Silverblue. I gave it a try.
But a long time ago Fedora client is distributed as a live image as the main image. A lot of spins.
I decided to try to re-assemble different live images for myself.
It is very simple and fast enough.
And it is easy to carry the distribution with you, you can easily load it on PXE, etc., etc.
Is there any point in Silverblue ? Maybe it’s easier to reassemble different LIVE-CD (can be done even with the settings from users) and just as you need to update the download ?
Live systems do not persist user data nor system configuration and can not be easily updated or rolled back in place. Silverblue solves all of those problems while keeping track of which packages are available in a given image and allowing you to easily add or change some. You can see it as a permanent and safely customizable installation of a LiveCD image.
Sure, you can persist user data outside of the system and access it remotely, but persisting system configuration and data is easier with Silverblue than with a LiveCD from my point of view.
Feel free to keep using a LiveCD if this is better fitted to your needs.
