That's a good question. Kinoite does not version some directories, such as your home directory or /etc. Rebasing and then reverting the rebase will create some clutter. What I'd suggest is to use some utility to version your files, perform a backup before doing the rebase or snapshot your home directory using the builtin snapshot functionality of btrfs. Maybe something like restic would work for this case.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

To add onto this, if you really wanted to rebase and don’t want config file clashes, you can use ostree config-diff after rebasing to show what config files changed. You can also simply remove all the files in /etc, and on the next boot, ostree will re-populate it with the contents of /usr/etc in a three way merge. Just be sure to copy, at bare minimum, /etc/shadow, /etc/passwd, and /etc/fstab otherwise it’ll be very awkward when you try to boot again and your boot process fails because it doesn’t automatically mount your disks and you can’t login because you have no users. It’s kinda cool tho, that, at least for this very specific issue, those 3 files might not be needed if/when systemd-homed’s JSON User Records and Discoverable Partitions see wider adoption.
(Note: this is dumb and error prone, and you should absolutely do what the other commenter said)
just a small correction, /etc does get snapshotted when upgrades happen and will roll back along with everything else. you are correct though that home does not get snapshotted and is fully mutable.
This is the main reason I don't generally rebase on anything except versions I intend to stay on if things work well. Yes, you'll keep your files and folders, but the updated software will write to them, and those will stay there too.
For example, new versions of Firefox might make modifications to your profile directory that might not work in earlier versions of Firefox. So if your rebase gives you a newer version, than reverting will break your Firefox profile.
(Now with Firefox specifically this isn't usually a problem, since even older OS releases will have the latest Firefox versions, and Firefox itself is pretty stable too, but the concept could also apply to other software.)
Leveraging flatpaks, as per the recommended workflow, largely negates these issues as well. Userspace apps shouldn't be impacted by the host OS changes in such cases.
It does, for the apps that are Flatpaks. But e.g. most of GNOME, and Firefox, are part of the immutable image at least for Fedora Silverblue.
I admit I typically hide the RPM Firefox and stick to the flatpak version. Aside from Nautilus though, in my experience most of the core GNOME user apps are provided via flatpak under Silverblue, including things like GNOME Calendar, Text Editor, Contacts, Totem, Evince, EoG, etc.
True; I'm mostly thinking about foundational pieces like GNOME Shell and settings, which could still wreak quite a bit of havoc. I don't actually know how often those introduce such breaking changes, but I'd rather not risk it.
Very important point.
This is also why you should not use toolbox but distrobox, and use a different home directory than your own.
Otherwise different OS versions etc. will give you dotfile conflicts like hell.
Home is mutable, and the mess that at least KDE does (not sure about GNOME) make removing its traces really hard.
I should write a script to remove all traces of KDE on a system, or to back everything up and import it etc.
Find me on Github if you want to help collect all the directories and files.
Its a total mess and can cause a ton of issues. The easy way to test DEs is to use a separate user account per Desktop. Lol.
That is what I feared. Using another user is a solution but it feels inelegant. I wish there were some middle ground, like being able to pin the home folder or something. I'll take a look at your github!
I had another idea, collect the locations (you can create a PR just listing them commented out) and then move the files to ~/.config/kde and hardlink (ln -S) them to the used locations.
Iconsets and maybe themes are also problematic and not directly KDE related, but these are the ones that cause compatibility issues.
I would also like to separate it between core Plasma (what Kinoite has installed) and the full KDE suite, and I would focus on core Plasma first.
I installed kinoite on my laptop. Rebased to silverblue for a while to try out gnome, rebased to kinoite rawhide to check out kde plasma 6, then back to kinoite 39. I think a few minor settings had to be redone, but no real issues.
Especially KDE and GNOME somehow mess up each others icons, so no this is not true.
These issues have to be fixed by the projects, putting their dotfiles in ~/.config/kde or ~/.config/gnome respecively.
I didn't have this experience? TIL
To be fair, all of that was in the course of less than a week, and I neither heavily use nor customize my personal laptop, so it's likely that if there are issues, I didn't encounter them.
Even so, I was quite impressed with how simple and seamless it was for me.
Did it, to bazzite, pretty painless. Yup, your config is the same. Immutable is indeed immutable.
No its not, /var/home is completely mutable, I think even entire /var and /etc are.
Ah, yes, bad phrasing on my part which assumed knowledge. The OS is immutable, but those three are mutable. I should also have pointed out it's prudent to spin up a new user if switching between Gnome and KDE due to dot file overlap, I'd be unsurprised if that applies to other DEs/WMs...
