I'm using the sbuild profile and my /etc/schroot/sbuild/fstab has the following
diff compared to the one from schroot 1.6.10-1:

% diff -u schroot-1.6.10-1/etc/schroot/sbuild /etc/schroot/sbuild/fstab

/tmp does not get mounted as tmpfs or bind mounted in this configuration (why
would I want my hosts /tmp in a chroot intended for building anyway?).
