Wouldn't rsync over SSH be better for this sort of feature
aggregation? The potential chroot caged setups for sftp may have their
uses, but the more complex you make this sort of behavior, the more
vulnerable you become to alarming failures such as leaving behind
temporary file debris as the artifact of a failed transfer, especially
in edge cases like transferring large files and the transmission being
interrupted or running out of disk space.
