            Bug ID: 11422
           Summary: Feature request: add support for Linux libcap[-ng]
           Product: rsync
           Version: 3.1.1
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
          Assignee: wayned at samba.org
          Reporter: rsync at sanitarium.net
        QA Contact: rsync-qa at samba.org

Linux has added a concept called file capabilities.  This allows certain
binaries to perform specific privileged functions without requiring SUID root.

# getcap /bin/ping
/bin/ping = cap_net_raw+ep

Rsync should be able to (optionally of course) copy these attributes as it can
copy xattrs and ACLs.  They should also be storable via --fake-super on
non-Linux systems.
