Running containerd-rootless-setuptool.sh install fails on Amazon Linux 2

[realvz]

I am trying to install nerdctl on Amazon Linux 2 using the full release archive. When I run containerd-rootless-setuptool.sh install, I receive the following error message:
[ERROR] Needs systemd (systemctl --user)

Here are the steps to reproduce the issue. Create an Amazon Linux 2 EC2 instance. SSH into it and run:

wget https://github.com/containerd/nerdctl/releases/download/v0.17.1/nerdctl-full-0.17.1-linux-amd64.tar.gz
sudo tar xvzf nerdctl-full-0.17.1-linux-amd64.tar.gz -C /usr/local

After this, running nerdctl throws this error:

FATA[0000] rootless containerd not running? (hint: use `containerd-rootless-setuptool.sh install` to start rootless containerd): stat /run/user/1001/containerd-rootless: no such file or directory

Then, running containerd-rootless-setuptool.sh install produces this error message:
[ERROR] Needs systemd (systemctl --user)

Its evident that the error has something to do with systemd

systemctl --user show-environment
Failed to get D-Bus connection: No such file or directory

Dbus (at least, the systemwide) service seems to be running
