[Bug 2165421] Re: /proc not mounted before installing packages for 26.10 buildd images

[Launchpad Bug Tracker]

This bug was fixed in the package livecd-rootfs - 26.10.10

---------------
livecd-rootfs (26.10.10) stonking; urgency=medium

  [ Allen Abraham ]
  * Minimize difference between imagecraft generated image and our current
    standard minimal Ubuntu cloud image.

  [ Michael Hudson-Doyle ]
  * The binary hook that installs udev for buildd builds now fails (because
    the hook does not mount /proc). But using a binary hook to install a
    package that ends up in every artifact is obtuse; so just add udev to the
    list of packages in auto/config and delete the hook (and the redundant
    installation of udev in 52-linux-virtual-image.binary). (LP: #2165421)

  This is happening during the run of the 03-network.binary hook when
  `udev` is installed
