Ok... how about on the IPL statement itself? Isn't there a way to pass
parameters that way?
While it may be possible, this exercise is silly to me, because I have the
CMSFS driven thing working. Just isn't being bought by the Head Sysprog
here. He's convinced doing it via CMSFS is going to bite us hard in the fleshy
part of the gluteus maximus some day.

I don't think there is any built-in support for passing queryable
parameters to Linux at IPL except for boot menu selection.

That won't work. The commands on [X]AUTOLOG are really designed for CMS
virtual machines (to satisfy the initial VM READ).
I would
DEFINE 1403 001
TAG DEV 001 PARM1=value1
Then IPL Linux and use hcp (cpint) or vmcp (builtin) 'tag query device
001' to extract the data.
