I still don't understand the internals of Guix to be able to comment
your patch, but...

this would be a nice to have feature!

maybe I'm asking too much... but would it be possible to load and boot
into the new (or another) kernel from the currently running kernel
without a reboot, via kexec?

something like https://wiki.archlinux.org/index.php/Kexec#Manually but
with a clean stop/restart of system services?

I know it could take some time (and maybe other things to patch) to have
this feature, but maybe it is worth thinking of it in connection with
this design change

Thanks! Gio'
