For me, I really want to get into niri, but the lack of XWayland support scares me (I know there’s solutions, but I don’t understand them yet).
Also, I stopped using Emacs (even though I love its design and philosophy with my whole heart) because it’s very slow, even as a daemon.
Bcachefs, and bcachefs on root. Need something with filesystem level encryption instead of LUKS, and *ubuntu’s and derivatives have all abandoned ZFS on root installs now.
Bachefs is in the kernel now so trying it on a spare drive or partition is super trivial these days depending on distro. You only need a few minutes of time.
Getting it on root is a bit harder as almost no installers support it yet. The only distro I can think of is CachyOS.
It’s far more ready than Wayland, get it into these distro’s installers! Are you listening, distros?
