sbuild with overlayfs fails in yakkety

[Dimitri John Ledkov]

overlayfs does not support renaming directories when the directories
live in the lower filesystem:

 * Directory renames only allowed on "pure upper" (already created on
 * upper filesystem, never copied up). Directories which are on lower or
 * are merged may not be renamed. For these -EXDEV is returned and
 * userspace has to deal with it. This means, when copying up a
 * directory we can rely on it and ancestors being stable.

This should be fixed for release, one way or the other.

See debian bug report for details.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

Try linux - 4.4.0-38.57 when it is promoted to updates.

[Dimitri John Ledkov (xnox)]

4.4.0-38.57 overlayfs sbuild appears to be good.
