Subject: debootstrap: better initialisisation of /etc/machine-id

Date: Mon, 29 Aug 2022 22:52:07 +0200

Package: debootstrap
Version: 1.0.123+deb11u1
Severity: normal

Dear Maintainer,

after debootstrapping, /etc/machine-id has a regular machine-id as contents
which seems suboptimal as its unreproducible and also, and foremost, this
can have nasty side-effects...

So probably it would be better to either remove the file or write "uninitialized"
into it... or support both via commandline flags :)

from #debian-devel today:

< bluca> for an image builder program, you can do two things with machine-id
< bluca> if you want the first boot logic to apply, you can initialize it to "uninitialized"
< bluca> if you don't want the first boot logic, have it as an empty file
< kibi> I think the behaviour changed between buster and bullseye; not sure what happened since
< kibi> (based on my recollection of 
        https://salsa.debian.org/raspi-team/image-specs/-/commit/26a7de63b0bb3de1b5d0c4d0529240721c322dbb for pi images)
<         Md> | h01ger: when creating an image it is better to have an empty /etc/machine-id than just deleting it, because 
              this way something can bind-mount a writeable file over it in early boot
<      josch> | h01ger: in case it helps, mmdebstrap writes "uninitialized" to /etc/machine-id
< bluca> empty -> no first boot semantics, uninitialized -> first boot semantics
< bluca> doc ref for the bug: https://www.freedesktop.org/software/systemd/man/machine-id.html#First%20Boot%20Semantics

Your reputable profile gives me the impression that you will be a suitable partner in a crude oil licensing operations venture involving the National Oil Company of Equatorial Guinea (GEPetrol) and the company I work for which is Sinopec Group. This venture will see us netting in $14m in Revenue approximately per transaction.


On your response I will give you clearer details of this operation. I can be reached directly with the following email account;  boey.mangue@gmail.com

Mangue Boey.
