Nothing should read /etc/hostname except /etc/init.d/hostname.sh during
boot. Everything else should use either uname(2) or gethostname(3)
(which in turn calls uname() internally).
For example, on NFSROOT setups /etc/hostname usually does not exist
to prevent the host name received from DHCP being overwritten.
