Yes, extended attributes and ACLs are really fun, but beware -- most backup programs currently still ignore EA and ACL data.
是的，扩展属性和ACL的确很有趣，但是，当心 ―大多数备份程序目前仍然忽略EA 和ACL 数据。
Using ACL gives more control on who can and cannot access or execute a file or directory; that is determined by the extended permissions that can be given to a file on a user or group basis.
通过使用ACL，可以更好地控制谁可以、谁不可以访问或执行文件或目录；这由按用户或组分配给文件的扩展权限决定。
To sum up, the scope of an ACL is at least the resource it secures, however the scope can be extended by an application in order to implement a designer's desired authorization model.
总之，ACL的范围至少是它保护的资源，不过，应用程序可以扩展该范围，以实现设计人员所需的授权模型。
If extended permissions is disabled, enable it. Convert the ACL type of test1.txt to nfs4.
如果禁用了extended permissions，那么启用它。
