Very true. I wonder if it might make sense to do a test at startup to
see if permissions are supported in the working directory and ignore
all permissions errors in the working directory iff the filesystem
would not preserve them anyway.
I also recognize that this is not a common usage scenario (I just
encountered it after using subversion for a long time), and I am not
highly inconvenienced by it. So if it warrants a bug in the tracker
with low priority, I would not be offended.

It did get me further. The results were as follows:
$ svn co http://svn.apache.org/repos/asf/subversion/trunk testdir

A /testdir/Makefile.in

svn: E000001: Can't set permissions on '/testdir/svn-o4bEud'
svn: E000001: Can't set permissions on '/testdir/svn-o4bEud': Operation not

The backtraces to the two errors are attached.
