AncientFS is a file system for MacFUSE that will mount all sorts of ancient file systems in the form of data containers as regular volumes on Mac OS X. “Examples of ‘data containers’ include file system disk images, tape images, incremental file system dumps, tape archives, and library archives.” You may then browse these volumes through the Finder as if they were regular volumes. They are read-only, and will preserve as many aspects of the original file system as possible.
In addition, Singh also introduced support for file systems in the System V and UFS families
