You could try filing a radar on this, but I suspect that the behavior's correct.

But I consider the ACL issue with rsync to have significant philosophical complications no matter how you slice it. Yet these are the most understandable and sane of rysnc's issues in Tiger.


I this this issue stems from:

uuid_to_name in file_cmds-116.9/ls/print.c

and in turn from mbr_uuid_to_id (see man page).

Also, nicl . -read /users|groups/whatever will show (for some users|groups) something called generateduid, which might have to do with the above.
I did another test: I used an ACL that referred to a group (admin for instance). It transferred fine. In this case the generateduid is the same on both (presumably all) systems. I also created a new group (this one without generateduid) and it also worked. 

No, not at all.

Don't pretend to "guess", either read the Internals book and/or the code. It's quite clear how users are identified. And nicl deals with netinfo.

So this is not an issue as long as:

1) one restores on the original system (that might not be possible, but one should also backup all the relevant system files)

or

2) one uses only group based ACLs (which is a good idea). Unfortunately there seem to be no way to specify a group acl when there is also a user by the same name. If somebody knows how to work around that please let me know.

It's not an issue at all, it's just you have a lot of woolly thinking going on.

I got excoriated for cross posting an announcement (expecting no replies) about the arrival of 10.4.9 (as a courtesy). Why then has no one complained about hijacking threads?

Well, hijacking threads on this list seems "de rigeur" for many newcomers, along with grabbing any thread of choice and hitting "reply all" in order to start a new one.

However, in reference to the above discussion, I don't see any hijacking as opposed to a discussion of rsync in 10.4.9 & its handling of ACLs, evolving into a discussion of ACLs in general. So more... worthy of a rename, but nothing was really hijacked there.

My 2 cents, take em or toss em as you please.
