In Subversion filesystems, it is not possible to change the kind of
a node. A node-revision with copyfrom must therefore be of the same
kind as the node-revision it is a copy of.
Similarly, when copyfrom isn't present, and the action isn't an add or
copy, then the kind of the thing identified by (PATH, REVISION) must
agree with the kind of the thing identified by (PATH, -1+REVISION).
Also, Subversion filesystems do not allow the root directory ("/") to be
deleted or replaced.
