It depends on the order in which you make your users
root is always user 0
the first user you make when you install (who will have sudo permissions) 
will be user 1000, the second 1001 and so on. Permissions of files are 
saved as the uid, not with names. So user 1000 on the new system will own 
the files user 1000 had on the old system. The name of user 1000 on the 
new system can differ from the name of user 1000 on the old system.
