Two empire falls recorded during the last two millenia it are the fall
of the mighty Roman Empire and that of the Ottoman Empire. Both were
extremely powerful influencing most of the worlds of their times, but
they fell.

What I expect from systemd and its adoption by many distributions is
to recognise its problems and work harder to implement any advantages
it may have had.

Like many Devuaneers (users and advocates of Devuan), I expect an init
system to remain an init system and package modularity to persist. I
also expect a predictable behaviour from an init system. On my
Raspberry Pi, systemd occasionally lists sound cards erratically
breaking their ID number.
