Bug Description

[Impact]

* The kernel changed the name of overlayfs to overlay and added the workdir
  option to the mount options.

* See https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ef94b1864d1ed5be54376404bb23d22ed0481feb

* This causes an error when running schroot:
  schroot --option=union-type=overlay
  E: /etc/schroot/chroot.d/click-ubuntu-sdk-15.04-armhf: line 12 [click-ubuntu-sdk-15.04-armhf] union-type: Unknown filesystem union type ‘overlay’

[Test Case]

* Try to run a schroot with option union-type=overlay:
  schroot --option=union-type=overlay

[Regression Potential]

I'm glad to see this was already fixed almost a year ago, but the version of schroot that is available in 14.04.3 with kernel 3.19.0-25-generic (schroot 1.6.8-1ubuntu1) is broken without it.

Is there a plan to push 1.6.10-1ubuntu1 to at least trusty-backports maybe?

summary: - schroot overlay v2 support
+ overlayfs: handle v3.18 overlay union type

This was fixed in Vivid. To fix this for Trusty, someone needs to create a debdiff for a Trusty SRU and follow the stable release update procedure here: https://wiki.ubuntu.com/StableReleaseUpdates

Hi, developers using Ubuntu 14.04 trying to install ubuntu-sdk are still facing this bug.

I post my trace when opening ubuntu-sdk

I´m looking for a fix and have been searching in the pending ubuntu stable release updates.
http://people.canonical.com/~ubuntu-archive/pending-sru.html

Can anyone create the debdiff for the Trusty SRU?

Thanks
