You'll need to run `usermod -u 1000 <username>` on your Ubuntu
installation to get Ubuntu's passwd file synchronized. You can do a
blanket change of the behavior by changing UID_MIN in /etc/login.defs
(odd location, likely historic).

Why does that sound like living dangerously? The distribution shouldn't
ever write there. You can generate config files that one doesn't like,
but the distribution tools /shouldn't/ do anything nasty without asking
you (since those are *your* files, and you're free to modify them).
