That's a bug in a lot of packages, yes. adduser has been designed to
allow adduser --system to be called without that logic:
If called with one non-option argument and the --system option, adduser
will add a system user. If a user with the same name already exists in
the system uid range (or, if the uid is specified, if a user with that
uid already exists), adduser will exit with a warning. This warning can
be suppressed by adding "--quiet".
So, just remove the extra getent passwd check and you should be fine.
