Public bug reported:
With the switch from out of tree overlayfs to in-tree overlay, sbuild-
launchpad-chroot must be updated to properly detect both of those,
otherwise users end up with a "directory" type chroot that doesn't use
unioning and so looses a few of the useful features provided by this
tool.
# Rationale
New kernel doesn't have a "overlayfs" module, it's now called "overlay".
Both names should be used in the detection code.
# Test case
- Before upgrade
- sbuild-launchpad-chroot create -n test -s xenial -a amd64
- Check that /etc/schroot/chroot.d/test doesn't contain "union-type"
- sbuild-launchpad-chroot remove -n test
- After upgrade
- sbuild-launchpad-chroot create -n test -s xenial -a amd64
- Check that /etc/schroot/chroot.d/test contains "union-type"
- sbuild-launchpad-chroot remove -n test
# Regression potential
Not much, this won't affect anyone who has existing chroots, it only affects
new chroots and re-introduces the behavior that people have been expecting up
until the time where the overlayfs driver was removed from the kernel.
