Hack to enable true auto-install for Ubuntu 20.04 with cloud-init nocloud
Raw

#cloud-config
runcmd:
- [eval, 'echo $(cat /proc/cmdline) "autoinstall" > /root/cmdline']
- [eval, 'mount -n --bind -o ro /root/cmdline /proc/cmdline']
- [eval, 'snap restart subiquity.subiquity-service']
autoinstall:

Thank you SO much for this hack... works like a charm for me with Ubuntu 20.04. It needs to be tweaked as follows for Ubuntu 22.04:

#cloud-config
runcmd:
  - [eval, 'echo $(cat /proc/cmdline) "autoinstall" > /root/cmdline']
  - [eval, 'mount -n --bind -o ro /root/cmdline /proc/cmdline']
  - [eval, 'snap restart subiquity.subiquity-server']
  - [eval, 'snap restart subiquity.subiquity-service']
...

That is, one first has to restart the subiquity-server before restarting subiquity-service, otherwise the 'autoinstall' added to /proc/cmdline won't be read. Thanks again.
