Yup, That's right. Anyone who knows how to put in a wildcard ?

Ah, eh, getattrlist is a POSIX constuct that noone but Apple seems to 
have bothered to implement.
It's like a getattr on steroids where the user process can ask about 
anything or nothins regarding a file system object, and get all the 
answers in a big chunk. Apple uses this in order to implement some 
Classig MacOS constructs (I Think)

I have looked at the get/setattrlist for ufs and nfs and decided that 
the implementation is not trivial. But it seems that Pekka's patch has 
solved the biggest prob÷em right now, without implementing getattrlist, 
so unless someone is very eager to code this, it looks as if it can 
wait for now.

I wanted to give Pekka CVS access, but he needs an OpenDarwin account 
before I can do that, and the portal with which you apply for such 
accounts seems to be broken. Thus, the patch isn't there yet. However, 
I'll try to put it in myself, unless Pekka disagrees on that.
