The native compilation part is the highlight. Could someone who knows about these things explain the difficulty Debian has in getting emacs 28 in -unstable ? (currently on 27 according to https://packages.debian.org/unstable/emacs)
I'm not a Debian developer, but did email Rob Browning some years ago, asking if he would perhaps consider trying to make it a team effort. I don't think I ever got a reply. I appreciate the work he's done to maintain Emacs in Debian for decades (!), but it would be nice if someone could give him a hand. For instance, it looks like 27.2 wasn't packaged despite being released a year ago.
This gives you guix "FD" and its great on top of debian for emacs especially (and you can move a lot of your emacs packages into guix as well).
The apt packages handles most of this but its good to follow along a little -
