Article Summary:
The article will describe how easyit is to switch between ostree-based variants of Fedora (Silverblue/Kinoite/Sericea) easy and secure with the availability of rollback in case if something goes wrong.
I did’t found this to be drscribed in any official website, but this is nice feature, so I think it is good to inform people about it.
Article Description:
The article will first describe how people can try different desktop environments while using traditional Fedora Workdtation not Ostree-based and drawbacks of the solutions:
- installing different desktop environment using
dnf- disadventages are: a lot of dependencies pulled in, cannot uninstall any desktop environment in easy way, doubled system apps in the application menu (e.g: Nautilus and Dolphin for browsing files) - dual booting multiple spins of Fedora - disadvantages are: lot of free space of hard drive consumed, have to maintain two copies of OS separately (e.g installing updates)
Next, the article will describe how ostree-based systems differs from non-ostree based (e.g immutable, transactional updates)
And the last topic, the article will describe how users can easily switch between ostree-based Fedora Spins (Silverblue/Kinoite/Sericea) to try different desktop environments using rpm-ostree rebase and describe advantages of this way:
- not much disk space consumed
- separation between OSes - no doubled system apps
- easy way to go back to the previous variant using
rpm-ostree rollback
