Thanks, that was a worthy exercise. Neither 'getty_ps' nor 'in.rlogind'
pass the "-p" flag to the 'login' program resulting in the behavior
environment-clearing behavior I had seen. Unfortunately, adding the "-p"
flag will have some other side effects such as HOME, PATH, and HIST not
being set correctly under 'getty_ps', so this requires a bigger fix than
I'd hoped.

Thanks. I need to address the above issue first and then will look at that
as an alternative to my original patch.

Thanks again!
