building an etch box

[Tim Jordan <tim@pcs-alaska.com>]

After building a debian box with the debian-31r1a-i386-netinst.iso I 
want to upgrade this box to unstable.  What is the correct way to do 
this?  I'm thinking I have to change my /etc/apt/sources.list to read 
unstable, but that didn't work.

Do I have to --dist-upgrade to testing first then update my sources.list 
and do another --dist-upgrade to unstable?

Thanks,
Tim
