This was an AT&T V7 kernel, with a number of bug fixes; new features in use at Berkeley; performance enhancements that were circulating to V7 in the licensee community; and build system changes. Based on the TUHS archives, it contains none of the V32 changes, however. In addition to the source code analysis, Mike Karels relates the story of how his group lost a customizes to V6 on a PDP-11/40 due to a disk crash. Since V7 just came out and Bill Jolitz had just brought that up elsewhere, they replaced their customized V6 with a V7 system, and that base would eventually become 2.8BSD. (Quarter Century of Unix) Given both lines of evidence, add a direct line from V7 Unix to 2.8BSD. Also confirmed that the V6 line to 1BSD and 2BSD was appropriate. 1BSD and 2BSD included ashell(1) and ex(1). ashell(1) was derived from v6 hell. ex(1) was an enhanced v6 ed. 2.8BSD included process control and user-land utilities from 4.1BSD Discussed with: Clem Cole, Diomidis Spinellis (dds) Differential Revision: https://reviews.freebsd.org/D30883 (cherry picked from commit 520a2401a65f94a2a6766d3a253baa2a1af0e54b) --- share/misc/bsd-family-tree | 29 +++++++++++++++-------------- 1 file changed, 15 insertions(+), 14 deletions(-) diff --git a/share/misc/bsd-family-tree b/share/misc/bsd-family-tree index 43715a00bb67..8e2ac27f945f 100644 --- a/share/misc/bsd-family-tree +++ b/share/misc/bsd-family-tree @@ -15,19 +15,19 @@ Sixth Edition (V6) -----* \ | \ | \ | -Seventh Edition (V7) | - \ | - \ 1BSD - 32V | - \ 2BSD---------------* - \ / | - \ / | - \/ | - 3BSD | - | | - 4.0BSD 2.79BSD - | | - 4.1BSD --------------> 2.8BSD +Seventh Edition (V7)----|----------------------* + \ | | + \ 1BSD | + 32V | | + \ 2BSD---------------* | + \ / | | + \ / | | + \/ | | + 3BSD | | + | | | + 4.0BSD 2.79BSD | + | | | + 4.1BSD --------------> 2.8BSD <-* | | 4.1aBSD -----------\ | | \ | @@ -498,7 +498,8 @@ Tenth Edition 1989-10-xx [QCU] 75 2BSD tapes shipped 2.79BSD 1980-04-xx [TUHS] 2.8BSD 1981-07-xx [KSJ] - + First 2BSD with bootable V7 kernel plus + community fixes. 2.8.1BSD 1982-01-xx [QCU] set of performance improvements 2.9BSD 1983-07-xx [KSJ]
