/bin/bash all the things. Since we are using bash syntax in some of the element fragments, we should make sure we use bash for all of them, so that things don't break on systems where /bin/sh != /bin/bash.

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. Change-Id: Ibc254fbb9e7b404b5f38c1b35bcde8a4136e8e28 2013-07-01 16:20:15 +00:00
Standarise tracing for scripts There is a wide variety of tracing options through the various shell scripts. Some use "set -eux", others explicity set xtrace and others do nothing. There is a "-x" option to bin/disk-image-create but it doesn't flow down to the many scripts it calls. This adds a global integer variable set by disk-image-create DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and turn on tracing. Any other tracing methods are rolled into this. So the standard header is --- if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then set -x fi set -eu set -o pipefail --- Multiple -x options can be specified to dib-create-image, which increases the value of DIB_DEBUG_TRACE. If script authors feel their script should only trace at higher levels, they should modify the "-gt" value. If they feel it should trace by default, they can modify the default value also. Changes to pachset 16 : scripts which currently trace themselves by default have retained this behaviour with DIB_DEBUG_TRACE defaulting to "1". This was done by running [1] on patch set 15. See the thread beginning at [2] dib-lint is also updated to look for the variable being matched.

set -u and -o pipefail everywhere As with the previous similar changes, this is intended to catch problems as they happen instead of ignoring them and continuing on to potentially fail later. Setting this on all existing scripts will allow us to enforce use via Jenkins. Change-Id: Iad2d490c86dceab148ea9ab08f457c49a5d5352e 2014-04-03 02:24:15 +00:00			`set -o pipefail`

Default name for ramdisks to image. If you build a ramdisk with ramdisk-image-create and forget to specify -o, you end up with a .kernel and .initramfs file as the image outputs. This commit defaults the $IMAGE_NAME value to image so you'd end up with image.kernel and image.initramfs Change-Id: I10f3ac9ad178c32119523e4da930070e3ade4f73 2013-12-04 18:45:29 +00:00			`IMAGE_NAME=${IMAGE_NAME:-'image'}`

Ensure we can read the kernel out. If the kernel is restricted read (as a security measure) we may not be able to read it without chmodding it. Change-Id: Ib577705c27d8c351288334de03a7848cf49f2de9 2014-05-13 16:25:05 +00:00			`sudo chmod a+r $TMP_MOUNT_PATH/tmp/ramdisk $TMP_MOUNT_PATH/tmp/kernel`
