10.4: Use Access Control Lists for fine-grained control
Authored by: sauron1440 on May 10, '05 03:52:53AM

The impression I gathered from the Ars dissemination was that the ACL data would be preserved by most (all?) HFS+ apps, as they use a fairly mature mechanism, the arbitrary metadata forks. I think permissions errors are going to be a little weird for most of the disk utilities, depending on how gracefully the Finder/kernel smacks them around for relying only on UNIX-style permissions. In other words, I would guess your data is safe as far as backup goes, but too much mucking with the ACLs will break most of the current generation of disk utilities.

Then again, this is all conjecture.
