I install Centos 7 machines through kickstart + a post install script. 
I do not need the gnome-initial-setup to run at all.

My post install script create a user and deletes the guest account.

When the uid of the newly created user is > 500 everything is fine
but when the uid is < 500 the gnome-initial-setup still shows up.

Can anyone tell me how to disable/configure gnome-initial-setup for

users with uid < 500 ?

Cheers,

Olivier DELHOMME.
