I am using cloud-init to initialize a RHEL Atomic Host VM.

I have the following as my user-data file:

#cloud-config
groups:
 - ourgroup
users:
 - name: muser
 primary_group: ourgroup
 lock_passwd: false
 sudo: ALL=(ALL) NOPASSWD:ALL
 ssh_authorized_keys:
 - ssh-rsa [REDACTED]
 - name: auser
 primary_group: ourgroup
 passwd: [REDACTED]
 lock_passwd: false
 sudo: ALL=(ALL) NOPASSWD:ALL
ssh_pwauth: True

When the VM boots up for the first time using an ISO file generated from that user-data file, the users are created. From what I see in /etc/passwd, the auser user is created with UID 1000, and the muser user is created with UID 1001.

We are deploying some software on this VM that needs to know the UID of muser in advance prior to installation. Whenever a VM is deployed using that ISO file, will muser always be created after auser (and therefore muser will always have UID 1001)?

I thought maybe the users were created in either alphabetical order or in the reverse order in which they are listed in the user-data file, so I created another user-data file with 4 users to test that theory. But that theory failed, and I could not tell in what order cloud-init creates the users.

If no one knows what order the users are created in, can I at least assume that muser will always have a UID of 1001?
