Starting with a personal attack that has nothing to do with the issue at hand? Trying to come up with some paranoid misinterpretation that adding some metadata in disk image files on the filesystem somehow makes the OS randomly mount and boot them? Come on.

If you can’t see a difference between feeling strongly about a technical issue and lashing out, good luck for your career.

Nowhere in this thread is there any mention of disk image files. Perhaps in a more emotionally contained discussion, we wouldn't have these misunderstandings.

If a disk image follows the Discoverable Partition Specification then systemd-nspawn has all it needs to just boot it up. Specifically, if you have a GPT disk image in a file foobar.raw and you want to boot it up in a container, just run systemd-nspawn -i foobar.raw -b, and that's it […]

Quoted in the post you’re responding to.

The blogpost cites eight different possible uses of the Discoverable Partitions Specification.

OP talks about "Use #2: Booting an OS image on bare-metal without /etc/fstab or kernel command line root=" and its potential pitfalls.

You appear to _think_ OP is talking about "Use #1: Running a disk image in a container", but quoting that part of the blogpost doesn't make it so.

If that's how you approach a complex topic, good luck for your career.

Seemed more like the OP admitting his bias than any kind of personal attack.
