While I'm at it I had might as well have the clean-bits map to a PP/extent disk arrangement which will act as a useful abstraction for a Logical Volume Manager / Veritas -esque disk management system which I also find interesting enough to code up. This is not an attempt to morph FreeBSD into AIX by any means. It is just an interesting project which I think may be of use to hackers. This month (02/98) I will explore the GNU HURD OS to see if their goal of creating an OS which would allow me to imple- ment a filesystem in user space has been realized. If it has not, I will use my normal FreeBSD 2.2.2 i386/40 and NetBSD 1.3 Sun 3/50 & 3/80 development boxes. Please let me know if I am duplicating effort and provide me with relevant pointers.
