The steps that previously worked back in January do not work on a F20
now? (I upgraded from F19 -> F20).

I'm using:
NetworkManager-0.9.9.0-45.git20131003.fc20.x86_64

and added these lines:

> > DHCP_HOSTNAME=wont-be-used
> > DHCP_SEND_HOSTNAME=no

to
/etc/sysconfig/network-scripts/ifcfg-<SSID>

Did anything change in this regard? How can I prevent hostname
disclosure via DHCP requests nowadays?

thanks!
