[ Steve Langasek ] * Add hooks to ubuntu-cpc to divert /bin/sync in the chroot and undivert it at the end. This is a general-purpose change that should be applied to all flavors and archs, but at the moment it's only needed on armhf+raspi2 to work around the raspberrypi2-firmware postinst calling sync, which is actually warranted in the normal case. * If a subarch is specified for a cloud image build, don't build rootfs artifacts; these should come from the 'generic' build. * Fix architecture handling in hooks. We know we're always being invoked from a launchpad-buildd-like setup, which passes ARCH and SUBARCH in the environment, because auto/config and auto/build both rely on this. So don't scatter dpkg --print-architecture calls throughout, especially when many of these are not cross-build-aware. * Refactor ubuntu-cpc hooks to allow us to handle images where the root partition should not be partition 1. [ Ben Howard ] * ubuntu-cpc: fix hooks/032-disk-image.binary call to create_empty_partition, which requires five args due to "-u" * ubuntu-cpc: in hooks/030-root-tarball.binary create /lib/modules to fix (LP: 1543204). [ Steve Langasek ] * Refactor ubuntu-cpc hooks to always produce a 'plain' rootfs via live-build and reuse this for the tarball, instead of lb_binary_rootfs creating some artifact that we ignore / throw away. * Initial support for raspi2 subarch. * Import live-build/ubuntu-cpc/hooks/raspi2/mkknlimg from https://github.com/raspberrypi/linux/blob/rpi-4.1.y/scripts/mkknlimg and use it to install a bootable uboot.bin.
