Am I right? Or are you going support more OS's in libattr? Or exists > here some similar library providing unified interface fro more systems? Note: I'm not the maintainer of libattr, so I'm not the one to decide. I think adding more systems is an excellent idea as it's a bit of a porting layer already. Russell will have to add FreeBSD support anyway once he ports xfsdump to FreeBSD :)
