According to Grant Erickson:

The problem I am having, which may be due to inappropriate hacking of
sysvinit, is that sometimes processes of which 'init' is a parent do not
inherit the environment variables exported:

They probably do inherit the environment, but simply reset the
environment internally ignoring whatever was set by the parent.

Has anyone else modified sysvinit in this way? Any success? Did I miss
something key in my patch?

I think you need to study the source code of those misbehaving programs.

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.

BTW, you could have achieved the same by using /etc/initscript. Could
be a shell script, but could be a small compiled executable too that
sets TZ.

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

Thanks again!

Grant Erickson
