Re: Good encapsulation, Dr S
"it might become impossible to do a simple systemd-less fork."
So don't use such a fork. Instead, use a distro that never implemented systemd in the first place. Simples.
I use and recommend Slackware. Try it. You might like it. There are other options; most won't cost you anything but a little time and bandwidth to try. Don't forget the BSDs and Minix (surprise!), they have viable options for most folk's desktops.
