pxe boot ubuntu installer with a preseed file:

walk away, 20-30 min later, ubuntu installed to the local drive.

Here is a shell script that does this to a VM:

I set this up for myself years ago, works great.  minor bit of work
each time a new release comes out, because the intaller will have new
options that need to be set in the preseed file.

There is no media involved (cd/usb stick...) so no making lots of
copies of stuff that get out of date.  it pulls from the repositories,
so the install has any security patches already applied.  I use a
P4-400 128mb, 6g drive as a server.  The requirements are that
minimal.  it basically takes the place of the install CD, and a
CD+drive is not a high end system.

When I first set it up, I documented all my configs on the ubuntu
wiki, which has been appened to till it;s a bit overwhelming:

Done let it freak you out, it's just a bunch of parts that work together.

I would be happy to swing by FreeGeek with the pxe server box ready to
go, show how it works for me, show where the various configs are, etc.
 I am out of town till Sep 19, so 23 would be the first Friday I could
be there.
