With the issues we are seeing with overlayfs V1 format support in v3.18 and later kernels we need to switch over to V2 format urgently for the liveCDs. See Bug #1410480 for details.

We need to evaluate whether we need this support in Trusty for the lts-vivid backport. It is likely we do not, but creating this task to ensure we review before the point release.

Andy,

 We need it in trusty, could help to backport it? Thanks!

Hello Andy, or anyone else affected,

Accepted casper into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/casper/1.340.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

---------------
casper (1.340.1) trusty; urgency=low

  * scripts/casper: move union content into a subdirectory of the /cow
    device, to allow us to create a workdir where that is needed for
    overlayfs. Also attempt to mount overlayfs with and without the
    workdir= to cope with the semantic change in newer kernels.
