That looks OK.

Do any of the files matching /etc/systemd/system/rsyncd.* or /lib/systemd/system/rsyncd.* exist on your system?

[postrational]

No, there are no files in /lib/systemd/system, they are in /usr/lib/systemd/system instead.

When I execute systemctl enable manually, I get the following output:

# systemctl enable rsyncd.service
ln -s '/usr/lib/systemd/system/rsyncd.service' '/etc/systemd/system/multi-user.target.wants/rsyncd.service'

Ok, that explains it - Webmin is looking in the wrong directory. I will fix this in the next Webmin release.
