> Moving between EZ directories should work fine if the EZ key for the
> directories is identical. If the key is name identical then no
> decrypt/re-encrypt is necessary.
> However, the rename operation checks more than the key name. It compares the
> inode number (unique identifier) of the source and dest dirs which will never
> be the same for 2 dirs resulting in the cited failure. Note it also
> incorrectly compares the key version.
> A related issue is if an ancestor of a EZ share the same key (ie.
> /projects/foo and /projects/foo/bar/blah both use same key), files also
> cannot be moved from the child to a parent dir, plus the child EZ cannot be
> removed even though it's now covered by the ancestor.
