Presumably any UNIX style filesystem would automatically provide this,
since a directory is essentially a file. Some filesystems, however,
allow for renaming a file without changing the encryption key...I think
Windows 2000 EFS works like this, for example. It seems to me that this
may open up attacks against integrity, e.g. via a kind of replay attack
where old versions of encrypted files are reinstated.
