Lately I have been experimenting with a Debian sid ppc64 system without systemd. Systemd is the default nowadays in Debian. In the old days all ‘services’ or ‘daemons’ were managed by init scripts. I was able to install sysvinit and to dump systemd from a base Debian install. I then installed a desktop (LXDE). It took me a while to get the network to work in LXDE but I know now how that is done. If people are interested I can make a page dedicated to achieving this in a verbose manner. The advantage of a systemdless system is a much faster boot, especially on these old devices we use.
