Critical Description
At least on NetBSD (see Problem Report pkg/40229), Subversion 1.5 doesn't work with repositories residing on NFS-mounted file systems (at least not with a NetBSD 4.0 NFS server). With 1.4, they do work. The problem seems to be related to the fix of Issue 1896. Due to NFS cacheing, files that have already been deleted may re-appear after the directory rewinding, causing svn_io_remove_dir2() to fail. Disabling the rewind apparently "fixes" the problem. I suppose one could either build a list of all files to be deleted beforehand, as suggested by Greg Hudson in the comments to said Issue; or, one could just ignore any ENOENT errors -- I can't think of any downside of that, but I might be wrong. The problem forces me to stick to subversion 1.4. I've brought up the subject on dev@ at http://subversion.tigris.org/ds/viewMessage.do?dsMessageId=2392271&dsForumId=462 and http://subversion.tigris.org/ds/viewMessage.do?dsMessageId=2398903&dsForumId=462 I will be happy to provide more detailed information (ktrace of svnserve, tcpdump of NFS traffic) should the problem turn out to be specific to NetBSD or other aspects of my installation.
