Created attachment 1700732 [details] dhcp6c@.service Please include a systemd service file for the dhcp6c service. I've included the service file I've been using for years.
Here is the currently included service file example https://src.fedoraproject.org/fork/bevhost/rpms/wide-dhcpv6/blob/master/f/dhcp6c.service I think I like your's better in that it uses %I. The existing one uses WantedBy=network.target which I think is better. The %I would allow it to be installed in /lib/systemd/system instead of the documentation folder.
Please note that I didn't write this service file. I think found it from this page: https://blog.dan.drown.org/fedora-based-router-with-dhcpv6-pd-support/ WantedBy=network.target seems better, I didn't had any trouble with basic.target though.
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle. Changing version to 33.
