Title:
  update-initramfs should produce a more helpful error message when
  there isn't enough  free space

Status in initramfs-tools:
  Confirmed
Status in Software Updater:
  New
Status in dpkg package in Ubuntu:
  Invalid
Status in initramfs-tools package in Ubuntu:
  In Progress

Bug description:
  Binary package hint: initramfs-tools

  When installing a kernel, /boot may become full during execution of
  post-installation script typically when update-initramfs is creating
  or updating an initrd.img file. This is resulting in kernel
  installation error.  For example:

  Setting up initramfs-tools (0.98.8ubuntu3) ...
  update-initramfs: deferring update (trigger activated)
  Processing triggers for initramfs-tools ...
  update-initramfs: Generating /boot/initrd.img-2.6.38-8-generic

  gzip: stdout: No space left on device
  E: mkinitramfs failure cpio 141 gzip 1
  update-initramfs: failed for /boot/initrd.img-2.6.38-8-generic
  dpkg: error processing initramfs-tools (--configure):
   subprocess installed post-installation script returned error exit status 1

  Ideal behavior:

  Give a more helpful error message when this unfortunate situation
  occurs so that user can fix the broken system and keep it going.
