描述

xattrs: Solaris 11 and OpenIndiana have the same API (O_XATTR):

Note that xattr/fsattr in sunos5 is far more powerful than on the other platforms. On sunos5 they are essentially file system namespace attached to every file. You can put any file type in there (e.g. sockets, block devices, link) and have arbitrarily complex directory structures. So it may make sense to map these into normal items (NUL as separator? - other platforms would not extract) and traverse them. Or, we could flatten them and only regard regular files (i.e. key-value pairs).

ACLs: APIs are also similar to each other (and our already implemented APIs)

研究方向
Examine Borg's platform specific code for xattr and ACL support in `src/borg/platform/`. Study the Solaris and Illumos man pages for O XATTR and acl APIs. Determine how to map the Solaris xattr namespace (which can contain any file type) into Borg's existing key value model. Consider the tradeoff between flattening and preserving directory structure. Look for any existing tests for other platforms to understand expected behavior.
