[Bug 1456443] Re: Skip eMMC device's boot0, boot1 and rpmb partitions

[Shih-Yuan Lee]

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]
  Installations on specific eMMC devices, where they are shipping with mmcblk0rpmb and mmcblk0boot* partitions. For example, Nvidia Jetson TK-1 ARM boards.

  [Test case]
  Attempt a server installation on the device.

  [Regression potential]
  Minimal; these devices are meant to be read-only and should be treated as such by partman, so it makes sense to explicitly filter them out.

  ---
  During installation,
  partman will scan all the available partitions.
  However, with the eMMC device, especially with its /dev/mmcblk0rpmb partition,
  a popup warning will show up to interrupt the whole installation process.
  One has to manually press the 'Ignore' button to skip that and proceed the installation.
  This seriously impacts some of OEM's auto installation requirements.
