AFAIK, Manjaro is not free enough to qualify for FSF endorsement. And
according to DistroWatch, it's not systemd-free either. I'm not sure whether
to trust that claim, however, since DistroWatch also claims that Linux Mint
is systemd-free, which makes no sense since Ubuntu already uses systemd and
Mint is an Ubuntu derivative.

If you're going to set aside FSF-level strict freedom criteria in search of a
systemd-free distro, PCLinuxOS is probably the most popular. Texstar has
firmly stated it won't use systemd.
