I was thinking that earlier with the netinstall of Trisquel but the server
optimized kernel was the big question mark in my original post. Is there
generally a huge difference in speed or memory usage?
What's the difference between desktop and server?
* The first difference is in the CD contents. The "Server" CD avoids
including what Ubuntu considers desktop packages (packages like X, Gnome or
KDE), but does include server related packages (Apache2, Bind9 and so on).
Using a Desktop CD with a minimal installation and installing, for example,
apache2 from the network, one can obtain the exact same result that can be
obtained by inserting the Server CD and installing apache2 from the CD-ROM.
* The Ubuntu Server Edition installation process is slightly different from
the Desktop Edition. Since by default Ubuntu Server doesn't have a GUI, the
process is menu driven, very similar to the Alternate CD installation
process.
* Ubuntu server installs a server-optimized kernel by default.
* Ubuntu Desktop will receive 3 years of support, while Ubuntu Server will be
supported for 5 years.
