The problematic dependency chain is this:
libgtk-3-0 -> libgtk-3-common -> dconf-gsettings-backend -> dconf-service ->
default-dbus-session-bus | dbus-session-bus
dbus-x11 Provides: dbus-session-bus, but apt prefers to replace
sysvinit-core with systemd rather than just install dbus-x11.
One way to reproduce this problem, in buster or sid:
1) clean chroot
2) apt-get install sysvinit-core
3) apt-get install emacs
If you install dbus-x11 right before attempting to install Emacs, apt
will not attempt the init system replacement.
