Remove cloudy interfaces in dhcp-all-interfaces Moves the code that removes default cloud interfaces into the dhcp-all-interfaces element. Having it live in stable-interface-names won't work right now because we need this for virtualized testing. Change-Id: I3166951c6fbb2faec53ffc339edd2fd0c3512300 2014-04-11 18:16:10 +00:00			`#!/bin/bash`

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 -e all the things Using set -e in all of our scripts will prevent some subtle bugs from slipping in, and will allow us to enforce use of set -e with tooling. This change also adds -u and set -o pipefail in the less complex scripts where it is unlikely to cause problems. A follow-up change will enable those options in the complex scripts so that if it breaks something it can be reverted easily.

Disable all interfaces on eni systems We are autodetecting and configuring devices in dhcp-all-interfaces so having one configured in /etc/network/interfaces by default is redundant and slows boot down. Change-Id: Ic4e8a0668c793d21ed2dd96908649c9a77264f67 Closes-Bug: #1239480 2014-10-09 12:33:01 +00:00
Add Gentoo to the dhcp-all-interfaces element This makes use of the dhcpcd package and it's ability to run on all interfaces by default. We disable the privacy extensions and dhcp overriding the hostname (both are enabled by default). Other than that it 'just works' and was the method used to bring up interfaces on Gentoo Openstack images before we switched to building with DIB.
