  This is also one of my primary reasons for wanting a new OS. 
  Among other interest, I got a kernel built last night and booted it.
Since I hadn't config'ed it for NFS mounted root, it died config'ing
the interface.
  I had to hack compat/sunos/sun_exec.c quite a lot though. The hacks
were obvious, I realized, and probably related to me making
sun3/machdep.c (er, or something like that) use the stuff from
compat/sunos/sun_exec.c instead of the 'local' COMPAT_SUNOS stuff.
  This confuses me since I know the Sparc people are using that code
aren't they? It relates to changes in exec.h. 
  Maybe I've mixed magnum and non-magnum stuff, I'm not sure.
