Title:
  omap netboot partition too small for flash-kernel backup procedure

Status in “debian-installer” package in Ubuntu:
  In Progress
Status in “debian-installer” source package in Precise:
  New

Bug description:
  [ SRU Justification ]
  omap netboot installs are broken, and it's only a matter of time and/or bad luck before a d-i spin on omap4 has a slightly larger kernel and, thus, the same problem

  [ Test Case ]
  Install using the d-i netboot image, watch it fail with the old images with the below errors, install with the new image, watch it succeed, an verify that the VFAT boot partition on the SD card is 72ish MB instead of 30ish.

  [ Regression Potential ]
  Very low, as I'm using the (exact) same partition size as the CD-ish media uses, which should satisfy boundary concerns, etc.  If it boots and passes the test case, it's fine.

  [ Original Descrpition ]
  Undecided if this should be fixed in flash-kernel-installer to be less broken when failing to create backups, or debian-installer to make the SD partition a bit (or a lot) larger.  Probably d-i's fault, as our CD/preinstall images use a 72MB SD boot partition, and d-i appears to use something closer to 32MB.

  At any rate, current precise on omap3 fails like so, and it's only a
  matter of time before the omap4 initrd gets large enough to cause the
  same issue, I suspect:
