Thanks for the detailed reply.  I should write my message clearer.  The issue
resides in /etc/rc.d/ structure, not dhcpcd(8) functionality itself.

/// short summary ///
When /etc/rc.conf does not have hostname= field, having
ifconfig_fxp0="dhcp" fails to assign hostname.

/// details ///
When /etc/rc.conf has dhclient="YES" and dhclient_flags="fxp0", dhclient
can assign hostname provided by DHCP server.  If /etc/rc.conf has
ifconfig_fxp0="dhcp" replacing the above two lines, /etc/rc emits the
following error message and the machine ends up with no hostname.

Starting Network.
/etc/rc: WARNING: $hostname not set.
