xattr and ACL support for Solaris 11 and OpenIndiana #1337
Description
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)

Is there anybody interested in this? It would at least need somebody testing this.
illumos/Solaris: add xattr support, see borgbackup#1337
Merge pull request #10102 from ThomasWaldmann/solaris-xattr-1337

xattr support is done (#10102) - if somebody uses some kind of solaris, please practically test this and give feedback.
ACL support is still TODO - anybody interested in having that?

This ticket seemed of really dubious value ten years ago, isn't illumos/solaris much dead-er today than it was a decade ago?

At least there is a working VM we use in CI.
It does even not crash when executing Python, unlike the NetBSD one.
Also, I had some tokens left to spend. :-)

There was no feedback about ACLs, thus I am closing this for now.
If somebody is interested in ACLs, comment below.
