Setting computer name in unattended.txt

I am going to deploy (upgrade to) Windows XP via a
distribution share using an unattended.txt file. I've
tested this and it works great. Here's my question. Do I
need a list of all the computer names that I am going to
upgrade in the file? If I leave the computer name section
blank, will the original computer name be retained during
the upgrade? In my test, I listed approx. 10 computer
names in this section, including the name of the computer
to be upgraded. when the upgrade was complete the
computer name was correct. I'm just wondering if I have
to go through the work of listing all the computer names
or if the upgrade simply keeps the original name and
ignores the computer name section in the unattended.txt.

Thanks for any insight,

Elly
