@mcc This might not be so easy. Systemd assumes that it has a lot of functionality available from the kernel (related to the various kinds of containers, process groups and namespaces) that aren't present in the various BSDs, so when Gnome became increasingly dependent on systemd this presented portability problems. Your proposed project (I know, not intended seriously) probably couldn't drop that much from Linux.
@not2b I simply want my computer to have less computer in it
