Hi Jakob,Hello Guys. I recently stumbled upon an error with NFS and --exclude-if-present. If the NFS-export contains a directory "lost+found", which is owned by root and has access rights rwx------ (0700) on the nfs-server, then no process on the client can access that directory (by default, as root is mapped to nobody). The selection function (Select.presence_get_sf in selection.py) that tests for the presence of a file however uses rp.readable() - which returns true, as the backup-process is root, and the directory is readable by root, according to its own metadata. The following lstat-call then throws an OSError-Exception (permission denied)... Below is a patch that should solve this problem. I would love to see this fix (or something comparable) included in the next stable rdiff-backup-version. If you have any more questions, please ask.

I don't think there is much active development going on (I'm not a dev here just a user).
Rdiff-backup is pretty stable and works well in a large set of conditions.
But having the patch out there might help someone so thanks for posting it.
