06e3d7c767 Add element ubuntu-signed to provide signed kernel
ubuntu-signed element would install 'linux-signed-image-generic' that
provides signed kernel that can be used for deploy in UEFI secure boot mode.

Package 'linux-signed-image-generic' ships signed kernel with extension
'.efi.signed' (Ex. '/boot/vmlinuz-3.13.0-49-generic.efi.signed').

The kernel modules directory for signed kernel and unsigned kernel is same.
It is without 'efi.signed' extension to its name. This is different from normal
practice of directory naming in '/lib/modules' (Ex. For signed kernel
'vmlinuz-3.13.0-49-generic.efi.signed', modules directory is
'/lib/modules/3.13.0-49-generic').
This needed some changes in '/lib/ramdisk-functions' and 'ramdisk' element to
copy kernel modules.

The signed kernel package contains both signed and unsigned kernel. The
unsiged kernel is without extension '.efi.signed' (Ex.
'/boot/vmlinuz-3.13.0-49-generic'). This required change into
'/lib/img-functions' and 'baremetal' element to pick up signed kernel version
when this element is used.

Sometime, we will get "Device or resource busy" during the mount point
deleting, umount return 0, but the resouce is busy for a while, so need
to add sleep interval to wait resource free, then we can delete it.

5671a38e8e Fix dhclient in Fedora ramdisks
Copy all of the necessary parts for a Fedora based dhclient to work. This
includes a number of network scripts. Also grab the ip command supplied by
the iproute package, the busybox "ip addr" command was missing the valid_lft
and preferred_lft options.

This will allow the dhcp to work in the ramdisk instead of getting passed the
PXE net config.

6337e6fe17 Fix issue with leaking /tmp/image.* directories
When building the ramdisk we don't cleanup the temporary
directories after ourselves. This leaves /tmp/image.* directories
mounted and /tmp/image.* directories on the system.

Also the ramdisk-functions duplicate, from what I can see,
the cleanup function from common-functions. So when a job
is killed off it ends up leaving /tmp/image.* directories
on the system.

eed30adc48 Enable dracut deploy ramdisks
The element builds dracut from source on Ubuntu because the
Ubuntu dracut package is broken and very old, so it can't be
installed properly and causes a number of other issues that
are fixed by using a newer version of Dracut.

This initial version should work in virtualized environments.
Further validation of its suitability for real baremetal
deployments will need to be done in the future, but this should
be sufficient to enable that work.

Regarding Dracut specifically, in order to limit the changes
needed in the existing scripts this element continues to use a
cut down version of the /init script that we were building for the
existing ramdisk.  However, instead of running it as pid 0 it is
run as a Dracut pre-mount hook.  This allows Dracut to set up all
of the hardware and system bits, while falling early enough in the
Dracut sequence to complete the deployment before Dracut would try
to boot off the hard disk.

3fada2566a Build raw image in separate tmpfs
If the tmpfs being used to hold the image filesystem is close to being
full then housing the raw disk image in the same place can be
problematic as it tends to grow faster then the filesystem shrinks when
data is being moved into it.

Putting them both into separate tmpfs's will allow there to be an
overlap where they jointly use more then the size limit for a singe tmpfs.

-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

9dcd13d45c Make copy_required_libs() more robust
On some systems ldd gives a slightly different output for VDSOs. It doesn't
contain a '=>'. E.g.:
   linux-vdso.so.1 (0x00007fff2f4a6000)
instead of:
   linux-vdso.so.1 => (0x00007fff2f4a6000)
This patch simply skips all entries in the ldd output which don't expand to a
path name to workaround that.

cleanup for ramdisk failed to umount TMP_BUILD_DIR with device or

The patch unmounts all the mountpoints under TMP_BUILD_DIR and
detaches loop devices associated with TMP_IMAGE_PATH.

The unmounts are applied with both force(-f) and lazy(-l)
options. Force option is only for NFS mounts, it's kept here since no
harm for lazy option.

56f4ef0851 Make sure sbin paths are in $PATH
The sbin paths (/sbin, /usr/sbin, /usr/local/sbin) need to be in $PATH.
Since $PATH is set in the build environment from the host, if the host
does not have these paths set, they need to be added to $PATH.  In
particular, they must be set for apt-get which calls out to ldconfig,
start-stop-daemon, etc.

The previous check was insufficient because if you had /usr/sbin or
/usr/local/sbin in your $PATH, the addition to $PATH was not done since
the "if" statement evaluated to true.

43c0082aa7 Move /tmp/ccache setup to base element
Commit c7d80dd (Cleanup mount points automatically) removed the unmount
of $TMP_MOUNT_PATH/tmp/ccache in run_d_in_target() and moved the
"rm /tmp/ccache" to elements/base/finalise.d/02-remove-ccache.  There
are two problems with this:

1) Not unmounting at the end of run_d_in_target() results in tmp/ccache
   being bind mounted muliple times on top of itself (three times, if you
   just run `disk-image-create base`).  It is eventually unmounted, but
   somehow the auto unmount code is confused, and tries to unmount it
   one more time than it was mounted, which results in an error like
   "umount: /tmp/image.THQkZxQa/mnt/tmp/ccache: not mounted".
   This doesn't actually break anything, but it's a little messy.

2) "rm /tmp/ccache" in elements/base/finalise.d/02-remove-ccache never
   succeeds in removing /tmp/ccache, because that hook is invoked by
   run_d_in_target(), *while* /tmp/ccache is mounted.

This present commit solves the above by moving the ccache setup glue out
of img-functions and into the base element's root.d.  This has the
following implications:

1) lib/img-functions is a little cleaner.

2) /tmp/ccache is available in the chroot during the root, extra-data,
   pre-install, install and post-install stages.  It is not available
   during block-device, finalise and cleanup stages as it will have been
   automatically unmounted by then.

3) /tmp/ccache won't be setup if you're building an image that doesn't
   include the base element.

e29cc0c10c Use lazy umount to avoid race problems with dev
A problem with unmounting the dev filesystem in Ubuntu images caused
the umount of the /dev bind mount to fail, which left it there to be
removed during the mv -t step, causing the build host's /dev to be
wiped out.

The lazy umount will detach it from the filesystem hierarchy and then
clean up the mount reference later.

dbfca7a816 Combine compress and save image into one function
When compressing an image, this is done in the same dir where the raw
image resides, doubling the amount of space needed (scarce when
using tmpfs), and then it's moved to the .cache folder in disk.

Combining these two functions, we reduce the amount of space needed
in the tmpfs partition (when in use), and the compressed image is
created directly on the .cache folder disk, so there is no need to
move the compressed image after the process into disk.

Most of our build process runs as root and the overhead of explicitly

operational overhead of keeping the sudoers.d file updated on build

Instead, we now document that the build process will expect sudo
commands to work and the operator must make this happen (either by
running as root, via sudo -E, or allowing passwordless sudo for the
build user).

b2f1d4e2af Document an interface for offline operation.
Complex image builds can download hundreds of MB of data from the
internet with many separate lookups. It would be nice to allow users
to ask for a fast build where those lookups are entirely avoided,
using locally cached resources (where possible). This new interface
allows users to signal to elements that they wish to operate without
updating cached resources, which will in turn allow us to avoid
checking for stale data at all.

As part of this I've also documented where we cache data, so that
things like the ccache cache dir and image cache files are not a
surprise to users.
