Changing only file permissions

First, make note that in the future always run rsync with at least
either --times or --archive.  If you had used --archive you would be
fine and if you had used --times then rsync could just fix the
permissions and ownerships (you would want to dry run first to make
sure that is all it wants to do).

Anyways, the tools you want are getfacl/setfacl from the acl utilities
package...

On the system that is correct do:
cd / ; getfacl -R . > acls.txt
Use your favorite method to transfer that file to the other system
then on it do:
cd / ; setfacl --restore=acls.txt

This will copy the owner, group, permissions, and any ACLs if you use
them from one system to the other.  Any extra files will be untouched.
 I think it will warn about missing files but I would have to test to
verify that.
