Hi,

sbuild maintainer here.

You mean you had to rebuild schroot, not sbuild, right? That patch is part of
the schroot source package.

This seems to be a schroot issue for which Roger Leigh is the best person to
talk to.

As for the sbuild part, maybe you want to try a different chroot backend? If
you can run a nested lxc, then you could try running sbuild like this:

sbuild --chroot-mode=autopkgtest --autopkgtest-virt-server=lxc \
    --autopkgtest-virt-server-opts="lxc-container [-- extra lxc-start args...]"

I'm personally not very familiar with lxc which is why I would like to get
feedback about using sbuild with the autopkgtest-virt-lxc backend.

Thanks!

cheers, josch
