Basically, I just followed this tutorial for my EndeavourOS installations. It's as easy as choosing an older entry in GRUB. Fedora offers something similar by default, and I think Tumbleweed does too.
Moreover I'm now playing with Arkane Linux (https://arkanelinux.org/), immutable flavour of Arch, it features another magic with btrfs and rollbacks without snapshots and GRUB
I use Btrfs for my root partition to be able to rollback if something goes wrong after update. XFS: in all other cases, since I hate the lost+found directory on ext4. Although I don't think there's any significant difference between ext4 and xfs in performance and reliability.

Actually, many people (or even majority) don't wear it nowadays. It's a protection against heat stroke, and if one doesn't visit a steam room one will be fine, though it's optionally even in a steam room, e.g. I never wore it.

If you want deb packages on arch, you can try use debian container through distrobox.
For 3 days lol, no breakages at all. I've switched from arch after using it for several months but now I just want stable enough distro with latest plasma and btrfs snapshots without hassle and decided to give tumbleweed a try.

One can't login to kbin server but can see posts from kbin in the feed, subscribe to kbin magazines and communicate with kbin users.
I think the question is about login to the kbin instance through the jerboa app, we're in the jerboa community after all. In this case it's theoretically possible to implement.
When I used Wayland my laptop couldn't turn on properly after sleeping. I think it's related to the fact that sddm (at least in standard repos) is xorg at the moment.
