The important thing is that the result from the command hostname is
within /etc/hosts (as in very very near the top).
On RH systems (I cannot speak for all others), the hostname is obtained
from /etc/sysconfig/network (hence the reason I used the cat command).
This hostname also matches up on the ip address for my NIC
(192.168.2.10) - They must exactly match.
the command 'hostname' merely prints whatever it obtained from
/etc/sysconfig/network and any subsequent operations that might change
that such as settings in /etc/sysconfig/network-scripts/ifcfg-eth0 or
commands such as 'hostname newhostname' but this last type of
modification is lost on next boot.
Thus it isn't about having coded .localdomain, but rather about a FQDN
(fully qualified domain name) and whether this fqdn matches the value
returned by the command hostname.
