Public bug reported:
recent amd64 server ISOs such as 20260402 shows a mismatch only on
./boot/grub/i386-pc/eltorito.img, where all other files are fine
I see in livecd-rootfs we do an explicit copy step on eltorito.img, and
as far as I can tell that does happen before actually run before the
md5sum.txt generation.
grub-pc-bin_2.14-2ubuntu2_amd64.deb contains
1351c46fcecbb024585dcc76319922b3 ./usr/lib/grub/i386-pc/eltorito.img
md5sum.txt actually says this, so matching
1351c46fcecbb024585dcc76319922b3 ./boot/grub/i386-pc/eltorito.img
eltorito.img on the iso has the md5sum ad194086c22ca4e20d23ed40e559480d
the two files have the following diff
--- eltorito.img (actual ISO file)
+++ ./ubuntu2/usr/lib/grub/i386-pc/eltorito.img (file from latest package)
