AFAIK softupdates have been part of freebsd since ver 3, thus long before UFS2!

Additions this article could now use:

  • Additions to UFS after FFS (I think they just increased field widths and added reserved fields)
  • More complete list of vendors who extended UFS
  • More complete list of proprietary features added to UFS for each vendor (as with above comment)

I'd add these, but I only have data for System V, Solaris, and Linux. SGI uses XFS instead.

Should this and FFS just be combined? As I remember, the first "UFS" was just the SunOS 2.0 version of the 4.2BSD FFS; 2.0 was the first SunOS version with a VFS layer into which file systems could be plugged (as it was the first one with more than one file system to plug into it, becaue 2.0 introduced NFS), and Sun called it UFS at that point. (It was definitely "UFS" in 4.0; I think that went back to 2.0.) Other commercial UN*X vendors probably picked up the Sun NFS code, which included a VFS layer, and probably also picked up the UFS name if they had FFS. The split of the code into FFS and UFS layers in BSD happened later. -- Guy Harris 01:17, 22 September 2005 (UTC)[reply]

I agree, merge. —Claunia 03:54, 2 January 2006 (UTC)[reply]
