[PATCH 0/6] Add support for Ubuntu

[Jan Kiszka]

As customers are asking for this, I sat down and refreshes Henning's
patches to enable Ubuntu images. These are now targeting the latest LTS,
20.04 Focal Fossa.

First downstream usage via meta-iot2050 is WIP.

If we get traction on this, ie. issue reports and contribution of newer
releases, we may consider making a Ubuntu a first-class citizen by
moving it over to meta. For now, meta-isar seems more appropriate.

The last patch in the series is not strictly needed for Ubuntu. I just
came across this while playing with linux-mainline for focal-arm64.

Ubuntu places the kernel and initrd links under /boot. Account for that.

On arm64, CONFIG_MTD is enabled but CONFIG_MTD_UBI is not. This leads to
a false negative in of the test that tries to disable CONFIG_UBIFS_FS.

Debootstrap uses scripts that usually have the same name as SUITE so we
never set them. In order to install a SUITE that an outdated version of
debootstrap does not (yet) know, we can tell debootstrap which SCRIPT to
use.
In fact many modern SUITEs will use SCRIPTS we might already have, we
just do not have the symlink to them.
i.e. "cosmic" uses the SCRIPT "gutsy" and a debootstrap from "stretch"
does know "gutsy" but not "cosmic"
So we can debootstrap SUITEs from the future, given they use a SCRIPT we
already have.

Ubuntu places kernel and initrd links under /boot. Furthermore, it makes
the kernel unreadable for non-root users. Account for the latter by
cat'ing the kernel under sudo, redirecting the output to the deployment
artifact so that it is owned by the building user.

Sweet. I do not like the distro (at all), but i like that Isar can
cater for it if need be. A few people seem to care ;)

Why "cat" instead of "cp"? I think the real trick is the sudo anyways.
