Public bug reported:
lsb_release -rd
Description: Ubuntu 18.04 LTS
Release: 18.04
I have a cloud-init file that creates a user and then tries to write a
file in the user's directory:
#cloud-config
# Hostname management
preserve_hostname: False
hostname: pspdr
fqdn: pspdr.local
users:
- name: student
home: /home/student
shell: /bin/bash
primary-group: student
groups: [ admin, sudoers ]
sudo: ALL=(ALL) NOPASSWD:ALL
write_files:
- permissions: '0644'
content: |
export LC_ALL=C
LOCALPY=$(python3 -m site --user-base)
[ -z \"$LOCALPY\" ] || export PATH=$LOCALPY/bin:$PATH
path: /home/student/.bash_aliases
owner: student:student
But the .bash_aliases file is created for root:root because it is
created before the user. Relevant parts in the cloud-init boot log are:

IMHO the execution order should be reversed
