As I feared when I heard it came from iX, it's *very* inaccurate.
For example, it claims that 1BSD was derived from 32/V (should have
been 3BSD), derives 1BSD from 1BSD and 4.1BSD (should be 4BSD) from
the second 1BSD (should be 3BSD), derives ``BSDI'' from 4.3BSD, when
in fact BSD/OS is derived from 4.4BSD, doesn't mention System V(.1) or
System V.3, etc.  And all this is OS code, not networking code.
