UFS started out as a layer on top of Berkeley Fast FileSystem (FFS), which was a derivative of the "FS" filesystem used in the first versions of [UNIX] at [AT&T]. It was introduced in the 4.4[BSD] distribution and is common in its derivatives, such [FreeBSD], [NetBSD] and [OpenBSD], as well as [Solaris]. The [Linux] [Kernel] only includes experimental support. |

[NetBSD] (since 1.5), [FreeBSD] (since 4.0) and [OpenBSD] (since 2.3) all employ an addition to UFS called SoftUpdates. SoftUpdates is which is a mechanism that allows a file system to safely use delayed writes for metadata updates. The results are consistent filesystems after powerloss/crash and much improved performance. |
