Ben Nemec 381ff6ab1d Fix set -eu and pipefail failures 
Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e.  This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

README.md

This is the base element.

Almost all users will want to include this in their disk image build, as it includes a lot of useful functionality.

Notes:

  • If you are getting warnings during the build about your locale being missing, consider installing/generating the relevant locale. This may be as simple as having language-pack-XX installed in the pre-install stage

  • This element ensures /tmp/ccache will be available in the chroot during the root, extra-data, pre-install, install and post-install stages. /tmp/ccache is unavailable during block-device, finalise and cleanup stages as it will have been automatically unmounted by then.
