** Description changed: + [Impact] + + In systems created from cloud images where cloud-init does not run (or + has not yet run), /etc/apt/sources.list does not have the same contents + as it has in a server install. This inconsistency can cause image + modification/bootstrap to fail. + + [Test Case] + + Examine the cloud image built from livecd-rootfs, and confirm that the + sources.list matches that in a server ISO install. + + [Regression Potential] + + Limited; the majority of cloud image usage does invoke cloud-init, which + already writes out a source.list that matches the server ISO. This + change aligns non-cloud-init usage to the existing norm. + + [Original Report] + When we were poking around under bug 1177432 we found that /etc/apt/sources.list that is built into the image does not match that of an installed system. This /etc/apt/sources.list is used if cloud- init did not re-write the file (such as woudl be used if you mounted the image directly and ran apt-get update). Example showing the problem: $ qemu-img create -f qcow2 -b wily/release-20151029/ubuntu-15.10-server-cloudimg-amd64-disk1.img /tmp/disk.img $ sudo mount-image-callback /tmp/disk.img --read-only chroot _MOUNTPOINT_ cat /etc/apt/sources.list deb http://archive.ubuntu.com/ubuntu/ wily main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ wily-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ wily-security main restricted universe multiverse What we'd like to see here is exactly what we just added to cloud-init. For reference, as attached to bug 1177432, see trusty [1] and wily [2] examples. For reference, MAAS installed systems end up getting the built-in /etc/apt/sources.list with the ubuntu mirrors updated. So this change after making it all the way through will result in maas images having the same list as ISO installed systems also. -- [1] https://launchpadlibrarian.net/224142290/trusty-sources.list [2] https://launchpadlibrarian.net/224142308/wily-sources.list Related bugs: * bug 1177432 [SRU] Enable backports in cloud-init archive template
