- DEPRECATED. The acl to set or remove. This must always be quoted in the form of '<etype>:<qualifier>:<perms>'. The qualifier may be empty for some types, but the type and perms are always requried. '-' can be used as placeholder when you do not care about permissions. This is now superseded by entity, type and permissions fields.

- The "acl" module requires that acls are enabled on the target filesystem and that the setfacl and getfacl binaries are installed.
