thanks a lot for testing the sbuild version in experimental!

The problem here is not with schroot but with sbuild. The version in
experimental decouples the location where the package is built from the machine
where sbuild was started. This in turn means that the machine running sbuild
does not have direct access to anything within the chroot anymore.

What you are seeing here is a remaining bug of this change.

Thanks for bringing it up - I'll take care of it with the next experimental
upload.

Until then, if you don't want to run sbuild with --no-run-lintian, please fall
back to the sbuild version from unstable.

Thanks!

cheers, josch
