In the report rsync seems to want to set mtimes, not permissions. > The bug report and extra info is at > http://bugs.debian.org/455194 .

My guess is that the problem has nothing to do with the munge-symlinks patch itself and it is just that the 2.6.9-5.1 package was built on a newer system. Specifically: A lutimes function to set symlink mtimes was recently added to glibc, and the underlying utimensat system call was added to Linux 2.6.22. Rsync's configure script checks whether the build machine's glibc advertises a non-stub lutimes function; if so, the built executable tries to set symlink mtimes. If a copy of rsync built on a machine with lutimes runs on a machine without it (e.g., kernel before 2.6.22), rsync will try and fail to set symlink mtimes. Thus, if the Debian build machine were upgraded to support lutimes between the building of the 2.6.9-5 and 2.6.9-5.1 packages, that would explain what users are seeing. Rsync 3.0.0 has been changed to ignore errors in lutimes calls to avoid harassing users in situations like this: http://git.samba.org/?p=rsync.git;a=commit;h=149a78e33f1632c8a3bdd00e10aecf69c8d5608d Debian could adopt this change or disable lutimes again for everybody by passing ac_cv_func_lutimes=no to the configure script.
