1 | After applying this patch, run these commands for a successful build: |
2 | ||
3 | autoconf | |
a30f8abd | 4 | autoheader |
f787c90c | 5 | ./configure --enable-acl-support |
fa26e11c WD |

9 | The program currently complains when the --acls (-A) option is used to copy |
10 | from a disk that doesn't support ACLs. This should be changed to silently | |
11 | notice that no ACLs are available to copy. Of course, trying to write out | |
12 | ACLs to a non-ACL-supporting disk should complain. | |
