For why BitKeeper could not be used, see:
  http://en.wikipedia.org/wiki/Git_(software)#Early_history

Before BitKeeper Linux used tarballs (for releases) plus patches (for
changes); patches were send by email (on LKML).  Some maintainers used
tools like Quilt (or custom scripts) for patch management.


P.S. FreeBSD (IIRC) used / uses CVS for version control, but it has
quite different development model than Linux.
