An [Acronym] for [Unix] FileSystem.
''InNeedOfRefactor: this page is mostly confused and needs
a thorough revision after
a good research
of the filesystem history
+ a a of the filesystem .
It was originally developed from the first versions of [UNIX] at [AT&T]. The FileSystem reached its current status in the 4.x [BSD] distributions. It it currently used in [FreeBSD], [NetBSD] as well as [OpenBSD] and the [Solaris] Operating Environment. The [Linux] [Kernel] only includes experimental support.
5.0 introduced UFS2, which allows FileSystem Snapshots, background fscking, as well as support for volumes over 1TB in size.
+[FreeBSD] 5.0 introduced UFS2, which allows FileSystem Snapshots, background fscking, as well as support for volumes over 1TB in size.
[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.
Some variants also referred to as FFS (Such as in NetBSD?)
