> Is it a chroot issue? Yes. In my particular case I was setting up a server for some non-technical users to share files with me via FileZilla. So I use ChrootDirectory %h to restrict users to their home directory. Even if it wouldn't be a security issue to omit this, my users would be confused by seeing the whole /usr, /bin, /var etc. directory hierarchy show up in FileZilla. And even if they could learn their way around it, I don't want them to see the whole directory hierarchy. I just want them to see their own files. Granted, this could be solved by symlinks if SFTP provided a way other than chroot to change the user-perceived home directory. But the fact that mount --bind works across filesystem namespace changes makes it more robust and useful in my book.
