We found recently that autofs does not play nicely with rbind, which led to complete removal of rbind from the profile fstabs in etc/profile-templates in the source. We now explicitly list each bind mount. I wasn't happy with doing this, especially since it's most likely a kernel bug. You actually end up with unmountable mounts, and need to reboot the entire system after running schroot since it's not possible to umount. We noticed this was occuring with rbind of /dev when using systemd, since systemd creates a number of autofs mounts under /dev. However, the problem affects all autofs mounts, not only those created by systemd. We can't be sure that the host isn't using autofs, hence we chose to go with the safe approach of not using rbind, and avoid the need to reboot the system to recover in such cases. Were the bug with binding of autofs mounts to be fixed, we would then certainly reconsider using rbind again. I'm not sufficiently familiar with the kernel to look at fixing it myself.
