That makes you a good candidate for surprise follow-up problems elsewhere. I’m wondering, if something is wrong with your DHCP / DNS service. systemd-resolved „knows“ there kind of hostnames: If you don’t touch the hostname during installation, you get a „transient hostname“ with fallback „fedora“, if the system get’s no hostname from DHCP, or a similar service. The transient hostname is evaluated at each boot time. If your DHCP service provides a hostname, it is used. Otherwise - just as a fallback - fedora is used. As soon as you define a „static hostname“, that hostname is fixed and will not be changed in the future (unless you change it explicitly), regardless what your DHCP server might deliver. If I remember correctly, the static hostname is synchronised with the classic /etc/hostname. Or maybe, it is a one-time action. And that is exactly the way, F35 works. I just tested the setup. (Usually I go the other path and define a static hostname in the installation process and the DHCP server picks that hostname and creates an DNS entry).
