well then for the people where networkmanager is not so nice to:
the following is an actual example and consistent over all my machines
with dhclient (4 desktops having the exact same output)

--- /var/run/nm-dhclient-eth0.conf --- (without dhclient-eth0.conf)
# Aangemaakt door NetworkManager

option rfc3442-classless-static-routes code 121 = array of unsigned
integer 8;
option ms-classless-static-routes code 249 = array of unsigned integer
8;
option wpad code 252 = string;

also request rfc3442-classless-static-routes;
also request ms-classless-static-routes;
also request wpad;
also request ntp-servers;
--- /var/run/nm-dhclient-eth0.conf ---

if NetworkManager does not do the trick, create the dhclient-eth0.conf
file or symlink and your hostname will be sent for sure
