            Bug ID: 11800
           Summary: smarter "safe" symlink detection
           Product: rsync
           Version: 3.1.1
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: core

We are using --copy-unsafe-links to sync a complex file/directory tree that
spans over multiple nfs drives to another site. However, --copy-unsafe-links
considers the following subdir1_link symlink as "unsafe":

|-- file1
|-- subdir1_link -> /nfs/dir1/subdir1
`-- subdir2
    `-- file2

subdir1_link is detected as unsafe and therefore its content is synced over and
over and therefore we get the following:


Is it possible to detect that subdir1_link is actually a "safe" symlink and
sync it as:

subdir1_link -> .
