And if I happen to not use Emacs (but > e.g. rsync) those handlers would not run, right? My question about this is (still) how do you use `find-file' (or something else) to open a file for editing, given just the inode/UUID? Such a thing could be recorded in a bookmark, but how to use it, to get to the file, with Emacs?
