"This feature, exclusive to Ubuntu Server Edition, is available
at the time of installation.The LAMP option means you don't have to
install and integrate each of the four separate LAMP components, a
process which can take hours and requires someone who is skilled in
the installation and configuration of the individual applications.
Instead, you get increased security, reduced time-to-install, and
reduced risk of misconfiguration, all of which results in a lower
cost of ownership.New pre-configured installation options have been
added to the postgreSQL Database options join existing Mail Server,
Open SSH Server,Samba File Server, Print Server, Tomcat Java
Server,Virtual Machine Host,Manual Package selection,LAMP and DNS
options for pre-configured installations, easing the deployment of
common server configurations."
