099493b62c Add dhcp support for ramdisk element.
This change adds support for retrieving the IP
through DHCP if 'ip' was not provided as a kernel
command-line argument by pxelinux.  This is used
when the kernel/ramdisk is booted by virtual media.

79ab95b16e Make sure all scripts are set -e
If scripts are not set -e then errors can be ignored, causing more
confusing failures later.

Also adds an exclusion comment to the ramdisk init script since we
don't want that to exit on failure.

1c07d4ba1a Remove All Rights Reserved
The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.

Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.

Remove all of the lines, because sanity.

9cb0615f38 indent: replace tab by 4 spaces
As decided in I072cf8bf6748d0c910fecffdf2282bcc4656d038, tab indent
should be avoided.

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.

d11c10fb6a Remove call to depmod in busybox
The version of depmod in busybox does not work if two versions of
the same kernel version are available, as search paths are not
honoured correctly.  However, we don't need to actually call
depmod as it's done during image building anyway.

8d910d10f8 Wait for tgtd socket to be available
tgtd returns execution control and backgrounds itself almost immediately
and before it has made it's listening socket available. This can cause a
race condition as the tgtd socket is not available when tgtadm is run,
resulting in an error:

failed to send request hdr to tgt daemon

Add a function to check if the socket is available before moving on to
calling tgtadm, and a wait_for helper function we can use.  We'll
check for the socket every 0.5 seconds, for up to 5 seconds.

I'm seeing this issue on almost every deploy using a ramdisk built from
Fedora 20. I'm not sure if something has changed in tgtd, but this
behavior is documented since Fedora 18 at least. In the systemd script
for tgtd, there is actually "sleep 5" to work around the problem.

09eb230ea3 Detect udevd version and behave accordingly.
We can no longer rely on the name of the udevd binary as a hint for its
version, so instead we query the binary and behave accordingly.

f093d4d38d Fix troubleshooting override.
We can now actually override the $TROUBLESHOOT environment variable in
ramdisks, by not declaring it as readonly. Yay for insufficient
end-to-end testing.

1f328087d9 Add troubleshooting override to deploy ramdisk.
We now allow operators to drop into a troubleshooting shell while
booting a deploy ramdisk, without having to have pre-configured their
desire to do so ahead of time, by means of a 10 second pause for them to
press a key.

c9f432d45b Split network bringup out of base ramdisk init.
We now run the network bringup portion of the ramdisk init from an
init.d script, thus allowing image builders to inject code into the init
script before that point (e.g. configure network hardware).
The environment variables used by the network bringup code are retained
in the base init script so they can be overridden by init.d fragments.

8d1ce9c0c3 Build ramdisks in an image chroot.
Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.

This fixes bug 1194055.
