The first item on the task list is looking at existing specifications and implementations, and that would include user management tools. I'm not sure if Sun and Apple chose the same extensions to chmod or not -- I'd probably guess not, but both should be looked at. Interestingly, Apple adopted parts of our POSIX.1e ACL library (or at least, its man pages) for supporting ACLs in applications, which surprised me as I felt that POSIX.1e ACLs and NTFS/NFSv4 ACLs were sufficiently different to make that somewhat difficult. > We may want to add the "Difficulty" part which was introduced in the passive > libpcap based TCP session anomaly detector entry. This is either a long task or a difficult task, but I think it's one even someone relatively new to kernel programming could work their way through. Implementing POSIX.1e ACLs was one of my first projects for the FreeBSD kernel, and while I have quite a bit more insight into ACLs now than I did then, I think it would still be relatively accessible given appropriate mentoring.
