UFS was reworked to support really big files and to bring in soft updates, we have UFS2 now and it's not going to change for a long time, their is some work at making a journaling UFS2 but if it became a default it wouldn't happen until FreeBSD 7. Big things like filesystems don't get change on point revisions so if it where to change it would be on the next major version, FreeBSD 6 has already been branched so we already know what it's major features will be and a different filesystem won't be one of them... they are still trying to get all of the filesystem utilities updated for UFS2, see here: http://www.freebsd.org/projects/bigdisk/ 1982; UFS 2003; UFS2 Post this message again in 19 years when we get UFS3.
