[Bug 1159016] Re: 64 bit live-USB successfully boots, but without persistence on UEFI pc

[oleg]

The (same) bug remains in trusty.  (For some reason the fix was only
applied to vivid, not trusty.)

Title:
  64 bit live-USB successfully boots, but without persistence on UEFI pc

Status in grub:
  Unknown
Status in usb-creator package in Ubuntu:
  Fix Released
Status in usb-creator source package in Vivid:
  Fix Released

Bug description:
  The 64but 12.10 2G live USB was set up on a 32bit 12.04.1 non-UEFI host with 1G persistence.
  The USB boots and persistence works on the non-UEFI host.
  The USB boots in Secure boot mode but without persistence on a UEFI host.
  The /proc/cmdline on the running live media shows the running kernel to be vmlinuz.efi.signed, which of
  course does not appear in any syslinux config files.
  Looks like something got left out in the secure boot procedure to have persistence.

  Live media created with the following iso:
  800063488 Mar 18 11:14 ubuntu-12.10-desktop-amd64.iso
  md5sum
  7ad57cadae955bd04019389d4b9c1dcb  ubuntu-12.10-desktop-amd64.iso

  The UEFI host is a Toshiba Satellite S855-5378 and has Windows 8 preinstalled,
  so no legacy BIOS is present.
