Your F8 machine has a /etc/sysconfig/network-scripts/ifcfg-eth0 file
then.  The system settings service will create automatic wired
connections for those devices that don't have any existing system
connection found.  So on your F9 machine, you do not have any ifcfg
files and thus the automatic connection is created.

s-c-n operates on ifcfg files, which are "connections" in NM
terminology.  Thu

It only works for system connections at the moment, but if you have
DHCP_HOSTNAME in your ifcfg file, it should pick that up and send it.
Verify this by dumping /var/run/nm-dhclient-eth0.conf and seeing what
options are in it.

On your F9 box, could you stop NetworkManager, 'killall -TERM
nm-system-settings', and the provide the output of the following
command?  You can Ctl+C it after about 10 seconds or so.

/usr/sbin/nm-system-settings --debug --plugins=ifcfg-fedora
