Systemd just doesn't integrate well into our system. The big advantage of using dmd is that it is also written in Scheme, giving us access to all of the features and libraries that Guile has. Our initrd is also written in Scheme, giving us the same advantages. There is a GSoC proposal out there to add support for some of systemd's file formats to dmd, for interoperability (and being able to run GNOME, notably). If any student reads this and wants to hack on an init system this summer, subscribe to our mailing list or hop on #guix on freenode and let us know.
