During installation I specified a hostname for the machine on my private
LAN but when I booted the hostname was localhost.localdomain
/etc/hosts was as follows:
127.0.0.1 myalias myalias.local.fqdn localhost localhost.localdomain
all on one line.
I had put in the private IP address and hostname during installation.
