In I084aff7e449f5de811a6169ec90e352ada7da439 we attemped to address a
bug for systems which dont have a path that works well for inside a
chroot. Turns out there were multiple issues:
* The PATH we were setting was after we attempted to call sh.
* PATH was being set in a sibling process to the command being run.
* PATH was not being exported so it was not effecting child processes.
Using env to set a sane path before we attempt to run our commands
addresses these issues.

The build host might not necessarily have a complete set of dirs
required in its PATH. It will likely be better to statically code a
complete(ish) set of PATH entries inside the function.
Some distros (ex: archlinux) are lacking some dirs commonly found in a
PATH. If this is used as a host OS, it will transfer this incomplete
PATH into the chroot, where other guests (ubuntu, centos) will fail to
find basic binaries due to the lack of a /bin entry.

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.

When uploading images to multiple clouds it is possible that the same
image will be needed in multiple formats to accomodate hypervisors
across clouds. Update disk-image-create's -t flag to take a list of
desired output image formats so that a single disk-image-create can
output all of the desired image formats.

The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.
Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.

In some instances, the content of the image may want to convey specific
resolv.conf settings. For instance, if unbound is installed, it's also
desirable to set resolv.conf to point to it.
Short circuit diskimage-builder's friendliness around resolv.conf files
by not dying in a fire if it finds the file to be immutable.

save_image is used to copy kernel and ramdisks out of the image, which
we will sometimes want to keep the source, and sometimes not. However
for the main image itself, the temp copy is never kept, so use mv
rather than cp and avoid the excess IO.

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.

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.

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.

want to drop to a shell in all cases but may only want to do so if one

then a user will be provided a in target shell taking over from where the
last failed command left off.

Setting up a routine to run at first time the system boot may vary from
distribution to distribution. This patch will remove the logic from the
diskimage-builder code and put it into the elements.
The base element will now deploy a dib-first-boot script and each OS
element will ensure that this script runs at rc.local time. By doing
that we will put the OS specific stuff in the OS elements and remove
the embedded code out of the img-function file.

With systemd rc.local lives in /etc/rc.d and is only run

Sudo compiled with the --with-secure-path option enabled (default on
Ubuntu, Fedora and potentially other distros) will cause sudo to ignore
any changes made to the PATH variable in the user's environment (even when
the -E option is used). Also, some distros might not have /usr/local/bin
set in their sudoers secure_path causing the diskimage-builder to fail
when building an image using such distros as host. This patch will force
the inclusion of the /usr/local/bin in the PATH enviroment variable
inside the chroot.
