Cannot Add User

I'm using Petalinux 2019.1 and trying to add a user. This recipe is within my own layer.

inherit extrausers

EXTRA_USERS_PARAMS = " useradd elton;"

The log has this to say:

I have attached a PDF to show how to do this on the ZCU102 in Petalinux

[kenny@stealthspacecompany.com]

I had read that post before and it is already what I am doing.

The PDF is another paint-by-numbers solution and it is not terribly helpful to engineers. It's also more or less what I'm doing except that I've added a recipe to a layer I've defined.

Ok, sorry it didnt help. These are the steps I took to get this working on my end.

You'll get this output manually when no arguments are given to "usermod". My guess is your Petalinux "do_rootfs" command is doing the same. It is worth looking into that.
