[Benjamin Drung]

set_linked_version in initramfs-tools 0.142ubuntu17 from noble has:

```
    linktarget=
    if [ -e /initrd.img ] && [ -L /initrd.img ]; then
        linktarget="$(basename "$(readlink /initrd.img)")"
    fi

    if [ -e /boot/initrd.img ] && [ -L /boot/initrd.img ]; then
        linktarget="$(basename "$(readlink /boot/initrd.img)")"
    fi
```

Title:
  kernel update fails when kernels from other distributions are
  installed in shared /boot

Status in initramfs-tools package in Ubuntu:
  Fix Released
Status in initramfs-tools source package in Jaunty:
  Won't Fix

Bug description:
  I have multiple linux distributions installed on my computer with a
  shared /boot partition. I have had this configuration working for a
  while now with ubuntu as one of the distributions. With jaunty,
  updates break the boot process every time there is a kernel update and
  dselect attempts to regenerate initramfs as it incorrectly selects the
  image from another distribution rather than the ubuntu image. The
  error message is as follows:

  Setting up initramfs-tools (0.92bubuntu21) ...
  update-initramfs: deferring update (trigger activated)

  Processing triggers for initramfs-tools ...
  update-initramfs: Generating /boot/initrd.img-initrd-2.6.27.7-desktop-1mnb.img
  Cannot find /lib/modules/initrd-2.6.27.7-desktop-1mnb.img
  update-initramfs: failed for /boot/initrd.img-initrd-2.6.27.7-desktop-1mnb.img
  dpkg: subprocess post-installation script returned error exit status 1

  
  In this case, deselect is trying to update the initrd image for Mandriva - instead of regenerating the ubuntu image: initrd.img-2.6.28-8-generic
