May I ask how you came to the conclusion that systemd is required to build Mutter with Wayland support?
Ah, just came across this:https://github.com/dantrell/gentoo-project-gnome-without-systemd/blob/master/README.md
This project delivers: GNOME without systemd and with basic functionality...The only feature which does not work is Wayland.
What would be so bad about systemd on Tiny Core Linux?
The only feature which does not work is Wayland.
The only feature which does not work is Wayland (unless you are using an elogind implementation).
elogind is a part of systemd. whether you drag all the parts of systemd in individually or infest the whole system once doesn't make a real difference IMO. it's still systemd.
Mutter can now be built with elogind. That is the systemd-logind as its own standalone package. This in turn allows using Mutter with its native Wayland back-end on Linux distributions using init systems besides systemd.
