40hz and other interested parties,
I was going to start another thread on the following (and may be I still will

), but if you'd like another fun rabbit hole that happens to use KDE, perhaps
NixOS would be interesting to check out. It appears to support XFCE (as well as other things), but KDE appears to be more the default.
I've been using its package manager,
Nix, on top of Gentoo mostly with happy results, but am also testing NixOS via VirtualBox.
not all roses...
Unfortunately, NixOS is also systemd-based -- may be someone will try to produce a version with OpenRC at some point...
