==Implementations==

Besides the UnixWare support, Martin Hinner wrote a '''bfs''' kernel module for [[Linux]] that supports it.<ref>{{cite web | url=http://martin.hinner.info/fs/bfs/ | title=UnixWare boot filesystem for Linux | author=Martin Hinner | date=1999 | publisher=Martin Hinner | accessdateaccess-date=2008-12-21 }}</ref>

He documented the file system layout as part of the process.<ref>{{cite web | url=http://martin.hinner.info/fs/bfs/bfs-structure.html | title=The BFS filesystem structure | author=Martin Hinner | date=1999 | publisher=Martin Hinner | accessdateaccess-date=2008-12-21 }}</ref>

The Linux kernel implementation of BFS was written by Tigran Aivazian and it became part of the standard kernel sources on 28 October 1999 (Linux version 2.3.25).<ref>{{cite web | url=http://ftp.linux.org.uk/pub/linux/iBCS/bfs/ | title=Linux Implementation of SCO UnixWare BFS | author=Tigran Aivazian | date=1999 | publisher=Tigran Aivazian | accessdateaccess-date=2018-06-14 }}</ref>

The original BFS was written at AT&T Bell Laboratories for the [[UNIX System V]], [[SVR4|Version 4.0]] porting base in 1986.{{Citation needed|date=October 2015}} It was written by Ron Schnell, who is also the author of [[Dunnet (game)]].{{Citation needed|date=October 2015}}
