Talk about the blind leading the blind.

Karl, it's NOT important to have that second line.

Many distros would have assigned multiple names to 127.0.0.1

However, since all 127.x.x.x addresses map to localhost (as I've explained
to you elsewhere) it is a convenience to add unique lines in /etc/hosts for
each name you use.

I take advantage of this for testing websites, by specifying:

127.0.1.1 bella.pointerstop.ca bella
127.0.2.1 nagisa.pointerstop.ca nagisa
127.0.2.2 plonevdc.pointerstop.ca plonevdc
127.0.2.3 nagisa2.pointerstop.ca nagisa2

Bella is my real hostname, and is the line that the Ubuntu installer
created.
Nagisa and PloneVDC are two websites I'm working on, and I can take
advantage of Apache's virtual hosts to get to the different web sites via
http://nagisa/ or http://plonevdc/ (or I can use the FQDNs for them). 
Apache's actually responding to requests on the "lo" interface - 127.0.0.1,
but gets the appropriate host name.  If I use http://localhost/ I get
something completely different.
