Seemingly Scott Long is working on journaling for ufs2. http://www.freebsd.org/news/status/report-jan-2005-mar-2005.html#Filesystem-journalling-for-UFS I like softupdates, conceptually (if they work correctly as described, which I do not know) but if ufsj can omit the fsck garbage collection after an unclean boot that would be a great boon. It would be nice if one can in the future chose between softupdates (for smaller filesystems) and journalling (for larger ones), or so. mkb.
