I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:
http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html
Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
to all 2.11bsd users:
when searching through the 2.11bsd code I wanted many times
a hyperlinked and cross referenced rendition of the sources,
much like doxygen or lxr does it. For kernel, lib and user
code, for c and assembler.
Since none of the existing tools seemed to do what I wanted
I wrote a perl script generating such a html'ized version of
the source code.
The tool far from finished, but starts to be useful. The
results from what I'd call an early alpha version are now
available. Just start with either the tar source
http://www-linux.gsi.de/~mueller/test/211bsd/usr/src/bin/tar.c.html
or the kernel init routine
http://www-linux.gsi.de/~mueller/test/211bsd/usr/src/sys/sys/init_main.c.ht…
and click a little around. The style sheet is still the debug
version, not all links end where they should.
The cross reference sections aren't complete, but already
useful. To see for example who is using setjmp see
http://www-linux.gsi.de/~mueller/test/211bsd/usr/src/lib/libc/pdp/gen/setjm…
or who is including nlist.h see
http://www-linux.gsi.de/~mueller/test/211bsd/usr/include/nlist.h.html#xref:…
The background color tells you in which territory you are in
magenta boot and standalone code
red kernel
orange network code (running in supervisor)
green libraries
blue user level code
Hope you enjoy it.
With best regards,
Walter
