Failure adding a user that is a member of the "users" group.

Bug

It appears you can't use the "users" group within passwd.users because it doesn't exist, or within passwd.groups because the group already exists. I assume that this part of ignition is not idempotent.

{"ignition":{"version":"3.3.0"},"passwd":{"users":[{"groups":["users"],"name":"core","noUserGroup":true,"passwordHash":"$1$$PsuPeH6mHmKdRxC/yQ6a0.","primaryGroup":"wheel","shell":"/bin/bash","shouldExist":true}]}}

Emits:

CRITICAL : ignition failed: failed to create users/groups: failed to configure users: failed to create user "core": exist status 6: Cmd: "useradd" "--root" "/sysroot" "--create-home" "--no-user-group" "--password" "$1$$PsuPeH6mHmKdRxC/yQ6a0." "--comment" "CoreOS Admin" "--gid" "wheel" "--groups" "adm,sudo,systemd-journal,wheel,users" "--shell" "/bin/bash" "core" Stdout: "" Stderr: "useradd: group 'users' does not exist
"

Whereas:

{"ignition":{"version":"3.3.0"},"passwd":{"groups":[{"name":"users"}],"users":[{"groups":["users"],"name":"core","noUserGroup":true,"passwordHash":"$1$$PsuPeH6mHmKdRxC/yQ6a0.","primaryGroup":"wheel","shell":"/bin/bash","shouldExist":true}]}}

Emits:

CRITICAL : Ignition failed: failed to create users/groups: failed to configure groups: failed to create group "users": exist status 9: Cmd: "groupadd" "--root" "/sysroot" "--password" "*" "users" Stdout: "" Stderr: "groupadd: group 'users' already exists
"
