Package: schroot Version: 1.6.4-4 If you have a directory schroot chroot whose source directory is the same as /, schroot's bind mount in /var/lib/schroot/mounts is invisible to file tree walking tools.
That is, rsync --one-file-system (rsync -x), cp --one-file-system (cp -x), find -xdev, etc., do not notice the mount point, and typically traverse through it. This is far from ideal. Now arguably this is a bug in bind mounts (perhaps a design bug). But as it happens it is easy to work around this problem in schroot in a way that is both correct and will fix almost all the problems: Move /var/lib/schroot/mounts to /var/run/schroot/mounts or some such. Typically /var/run is a tmpfs. As a result there will be a filesystem with a different devid between / and the chroot. So to all the file tree walkers, it will look like two mount points. Backup tools, find, etc., will not descend into schroot's bind mount because they'll stop at /var/run.
