Title:
cloud-config script not executing: cloud-final.service not reached
Status in cloud-init:
Expired
Bug description:
From the mailing list archive: https://lists.launchpad.net/cloud-
init/msg00385.html
Here's the debugging information based on Chads' response which may
not have been delivered to the list. Note that I have to type out the
details due to firewall and network details. It looks like everything
is ok based on described. I do have to run the script as root for it
to succeed. However the first command to write the dummy file doesn't
require root.
To debug further where should I specifically look for a log that
captures the run command script execution after Shellification?
Is there a way to capture any errors or even the script run itself?

1. Yes
#cloud-config
runcmd:
- echo "cloud-config" > /tmp/cc
- sudo mkdir /lps
- sudo mkfs -t xfs /dev/nvme2n1
- sudo chmod 777 /etc/fstab
- sudo echo "/dev/nvme2n1 /lps xfs defaults 0 0" > /etc/fstab
- sudo chmod 544 /etc/fstab
- sudo mount -a
- sudo chown -R logr:logr /lps
- sudo chmod -R 744 /lps
output : {all : '| tee -a /var/log/cloud-init-output.log'}
2. Valid cloud-config: system userdata

when I look at /var/lib/cloud-init.log I see relevant lines that
tell me
util.py start: modules-config/config-runcmd: running
config--runcmd with frequency once-per-instance
util.py Shellified 9 commands
Writing to /var/lib/cloud/instances/....
main.py Ran 14 modules with 0 failures
Don't see any errors
4. when I manually try to inoke the script without sudo
-bash : /var/lib/path/to/instance/run-cmd : Permission denied
I checked the ownership. The file is rwx owner, and owned by root root
When I execute the script at /var/lib/path/to/instance/run-cmd using
sudo, it runs as expected.
