Comment 10 for bug 153310

If a non system user already exists user-setup-ask does terminate immediately. This is caused by is_system_user in functions.sh in /usr/lib/oem-config/user

Overriding is_system_user like this will allow to generate a second user during oem-config-firstboot:

# Workaround when there is a user between 1000-29999
is_system_user() {
 return 1
}
