If `/dev/` is mounted with `--bind` (like it is common for `chroot` environments) device in `/etc/fstab` in the `chroot` appear in the `unity` sidebar no matter whether they have been removed from it previously. After a reboot the initial appearance settings are overwritten (at least previously removed devices are displayed again). `unity` should not care about `chroot` setups and not overwrite settings without asking.
