ubuntu-23.10-preinstalled-server-arm64+raspi.img contains pre-seeded machine-id

Asked by @AT

Ubuntu mantic-server-daily and 23.10 server Raspberry Pi preinstalled image has some issue that breaks some deployments. Image contains pre-seeded "/etc/machine-id" and /var/lib/dbus/machine-id files. This means all instances deployed from this image will have the same machine-id and all randomly generated attributes based on machine-id.
Related to https://man7.org/linux/man-pages/man5/machine-id.5.html, machine-id file must be empty, or contain string "uninitialized" at first boot to generate unique machine-id, or /etc/machine-id should be empty in case of network boot.

In my case, all systems deployed using 23.10 image generate the same MAC addresses for network bridges with the same names, making them inaccessible due to MAC address conflicts.

I suggest to update image building process to seed /etc/machine-id file with "uninitialized\n" string and remove /var/lib/dbus/machine-id from the image.

P.S.
ubuntu-22.04.3-preinstalled-server-arm64+raspi.img has /etc/machine-id file with empty content.

1. Ignore comment #1. That is spam.

2. As far as I know, the daily images are not meant to serve as the basis of a wide-scale deployment.
In any case, I suggest that you create a bug report, I assume that https://bugs.launchpad.net/ubuntu-cdimage/+filebug is the best address for doing that.
