Support for Unix ACLs?

[danmoseley]

What is our story for ACL's on Unix, where file system supports it?

Mono.Posix (what we point at for API for Unix primitives) does not support them. Do we need to offer support for them somewhere?

Whereever that support lies, do we need to add extension methods (like this) to allow objects to be created with the ACL applied? If not, what is the story for folks porting Windows code using ACL's to Linux?

This assumes we do not want to attempt to overload types like DirectorySecurity, which were designed with Windows in mind, to accommodate Unix.

The first question here is whether there is any interest, perhaps we can gather that here if any.

Triage: Conceptually we want to have ACL support for Linux (see RedHat's support). The reason we haven't done this yet is that there isn't Posix support yet and there hasn't been significant asks from customers yet.

If we do it we'd also want to see if we can provide some sort of common abstraction with the existing Windows ACL support.
