Simply put: tough. If you have to have non-root ownership and/or write
permission to the top of the chroot cage, then don't use SFTP. Use
ftps, supported by vsftpd, which has a different security model and
suports an enitely empty workspace fo FTP-like uploads or downloads.
For Linux and UNIX systems, the "vsftpd" daemon does this very well. A
genuine ftp or ftps server does not have some of the powerful features
of an an SFTP server, but can handle symlinks considerably better.
