After applying this patch, run these commands for a successful build:
- autoconf
- autoheader
+ ./prepare-source
./configure --enable-acl-support
- make proto
make
-The program currently complains when the --acls (-A) option is used to copy
-from a disk that doesn't support ACLs. This should be changed to silently
-notice that no ACLs are available to copy. Of course, trying to write out
-ACLs to a non-ACL-supporting disk should complain.
+See the --acls (-A) option in the revised man page for a note on using this
+latest ACL-enabling patch to send files to an older ACL-enabled rsync.
