Re: On the man page mention -readable by whom

Find uses access(2) to implement -readable.   Unfortunately that doesn't
actually translate into a guarantee that the file can really be read by the
find process (or the user running it) among other reasons because NFS
clients have no way (in NFS <= 3 at least) to apply the same set of access
control checks that the server does.   Root squashing, for example.

So while, yes, a clearer description would be helpful, it's not quite as
simple as "by whom".  As always, a specific suggestion for a change in the
form of a patch is very welcome.
