Adding --ignore-uid-mismatch or some such would be easy enough to do,
but it seems like the right thing to do here is to just make your
scripts use --no-create-home.  This will skip this code path
altogether, and seems like the right thing to do if you ship the home
directory in the package anyway.  This is what I do in my packages that
create users and also have the directory in the deb.

Take care,
