Bug Description

Binary package hint: livecd-rootfs

Havoc Pennington reported that /var/lib/dbus/machine-id needs to be unique across instances of the running live CD, and between installed systems. The simplest way to ensure this is to remove it from the live filesystem.

We do have an upgrade problem, though; a number of people will have installed from previous versions of the live CD and will have duplicated machine-ids, although we can't feasibly identify the list of machine-ids involved (and it would be huge). I'm opening a task on dbus as well to figure out how to do something about it on upgrade. Maybe the answer is that everyone should have their machine-id forcibly regenerated on the first boot after upgrading to some nominated version of dbus?

livecd-rootfs (0.77) jaunty; urgency=low

  * Remove the D-Bus machine identifier from the livefs; it needs to be
    unique, and it's generated at boot time if it's missing (LP: #322830).

We never took a decision that, and missed the release boat.

Should we still forcibly change everyone, or just close this bug now?

In Lucid testing:

got problems with dbus & dbus-x11: miss dependencies but don't know which ones, maybe false warnings or not real raisons.
So trying to reinstall those packages in a chrooted space, i fail again saying partial installation.

Removing then reinstalling those packages + ubuntu-desktop to get back all the additional removed packages, i've had a lot of warnings and many packages failed to install : dbus, polycykit, ...

because of : /var/lib/dbus/machine-id ( running: dbus-uuidgen > /var/lib/dbus/machine-id don't resolve it)

This has recurred in Oneiric due to the switch to live-build. :-(

casper needs to generate the machine-id early on, otherwise a few things it does (such as removing the screensaver lock with gsettings) fail.

---------------
live-build (3.0~a24-1ubuntu17) oneiric; urgency=low

  * Remove /var/lib/dbus/machine-id in lb_chroot_hacks to prevent every
    machine installed from our media having the same ID. This is a
    regression from the previous livecd-rootfs behaviour (LP: #322830)

We decided not to make casper generate machine-id after all, because nothing in casper should be relying on dbus being running. Instead, these fixes dealt with the fallout:

casper (1.287) oneiric; urgency=low

  * Remove typo from 26disable_user_menu that led the script to
    believe that indicator-session was never actually installed.

casper (1.286) oneiric; urgency=low

  * Convert the gsettings calls to using the gsettings override files
    because we don't have DBUS in casper.
