1 | After applying this patch, run these commands for a successful build: |
2 | ||
27e96866 | 3 | ./prepare-source |
f787c90c | 4 | ./configure --enable-acl-support |
fa26e11c WD |
5 | make |
6 | ||
f05cc718 WD |
7 | The program currently complains when the --acls (-A) option is used to copy |
8 | from a disk that doesn't support ACLs. This should be changed to silently | |
9 | notice that no ACLs are available to copy. Of course, trying to write out | |
10 | ACLs to a non-ACL-supporting disk should complain. | |
