I didn't use any preseed config. I just download the mini.iso and make an installation USB stick by it.
Then I plug the USB stick into a laptop that only has an eMMC system storage inside to do the installation test manually.
During the installation, I will connect to Internet to download other udeb packages and this is the usual usage for mini.iso.

http://archive.ubuntu.com/ubuntu/dists/wily-proposed/main/installer-
amd64/current/images/netboot/mini.iso works and /proc/version_signature
shows "Ubuntu 4.2.0-16.19-generic 4.2.3".

http://archive.ubuntu.com/ubuntu/dists/vivid-proposed/main/installer-
amd64/current/images/netboot/mini.iso doesn't work and
/proc/version_signature shows "Ubuntu 3.19.0-30.33-generic 3.19.8-ckt6".

http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-
amd64/current/images/vivid-netboot/mini.iso works and
/proc/version_signature shows "Ubuntu 3.19.0-32.37~14.04.1-generic
3.19.8-ckt7".

http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-
amd64/current/images/utopic-netboot/mini.iso doesn't work and
/proc/version_signature shows "Ubuntu 3.16.0-52.71~14.04.1-generic
3.16.7-ckt8".

http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-
amd64/current/images/netboot/mini.iso works and /proc/version_signature
shows "Ubuntu 3.13.0-67.110-generic 3.13.11-ckt27".

It is expected that "Ubuntu 3.13.0-67.110-generic 3.13.11-ckt27",
"Ubuntu 3.19.0-32.37~14.04.1-generic 3.19.8-ckt7" and "Ubuntu
4.2.0-16.19-generic 4.2.3" work and "Ubuntu 3.19.0-30.33-generic
3.19.8-ckt6" doesn't work.

It is not expected that "Ubuntu 3.16.0-52.71~14.04.1-generic
3.16.7-ckt8" doesn't work but we don't maintain utopic now so it is
probably OK.

The only problem left now is that http://archive.ubuntu.com/ubuntu/dists
/vivid-proposed/main/installer-amd64/current/images/netboot/mini.iso is
not up to date.

Bug description:
  [Impact]

   * The users can not use netboot.iso to install Ubuntu on eMMC
  storage.

  [Test Case]

   * Download netboot.iso of trusty/utopic/vivid from http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/
   * Use netboot.iso to burn an installation CD/DVD or make an installation USB stick.
   * Use this installation media on a platform with eMMC storage to install Ubuntu system.

  [Regression Potential]

   * None

  [Other Info]

   * None

  Linux kernel in Ubuntu doesn't provide mmc-modules udeb like https://packages.debian.org/unstable/mmc-modules-4.2.0-1-amd64-di in Debian.
  So it makes us unable to install the Ubuntu system into eMMC storage via netboot, aka http://archive.ubuntu.com/ubuntu/dists/wily/main/installer-amd64/current/images/netboot/.
