Move the dpkg specific stuff to a dpkg element rather than being hardcoded. This includes the install-packages implementation for dpkg, apt http proxy config, daemon blocking and unblocking. Change-Id: I8f159021d2b223d7003cec067de3aa605ad06974 2013-02-13 22:16:00 +00:00			`#!/bin/bash`

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 -eu`

Uses policy-rc.d to prevent dpkg starting daemons Currently the dpkg element fakes start-stop-daemon, initctl and invoke-rc.d to stop dpkg from starting a bunch of daemons in the chroot. This is problematic when packages use service, start, stop or restart commands. This patch uses a policy-rc.d instead of faking invoke-rc.d to achieve the same thing. This approach now aligns exactly with debootstrap. Without this patch DIB runs on some debian distributions fail when trying to umount the chroot loop device as there are daemons running. The log will now show "invoke-rc.d: policy-rc.d denied execution of start." instead of "Warning: Fake invoke-rc.s called, doing nothing."

Don't block the upstart daemon if it doesn't exist Check if Upstart exists before blocking the daemon. Not all dpkg based OS's have Upstart installed so this should help increase compatibility.
