Do not use job control.  Either undefine it, or, in your .kshrc, put in a
'set +m'.  The problem, once again, is that job control in 3.2.0 and 3.2.1
(which is what ODT 1.0 uses as a kernel) is so completely broken that it has
no chance of working.  Preferably, btw, you would upgrade your OS, at least,
to 3.2v2, which has working job control and includes ksh.

Yes, that's right.  The ppid:  the parent process.  Its parent has died,
so it gets process 1 as its parent.  This is normal for unix.

I did get ksh working for 3.2.0; however, I did that as an attempt to get
job control working, and my kernel never made it very far outside of the
office 8-).  But, if you are set on using ksh with odt1.0, all you should
need to do is the set +m I mentioned above.  (This prevents ksh from doing a
bunch of things, including putting each command set into a different process
group).
