You can boot into single user mode and do either of the following:

1. Delete the user created at install, modify "/etc/login.defs", and
re-create the user. (Only useful at first boot!)

2. Modify the uid of the user,  modify "/etc/login.defs", and chown
the user's home directory recursively with the new uid.

(You may also have to edit "/etc/adduser.conf" if you use adduser
rather than useradd.)
