Here's an esoteric question for the SRM gurus in the audience.
As you know, the SRM has some handy environment variables that
live in the flash ROM. These store default strings for the
boot device, kernel arguments, etc.
My question: Is there any way to read and write the values in
these SRM environment variables from a C program running under
Linux (i.e., after the kernel has booted and the system is up
and running)? If so, how?
The reason I ask is that I have a 16-node cluster of LX machines,
all but one of which is headless, and there are occasions when
it would make life a lot simpler if I could change the SRM
environment variables from a C program under Linux, rather than
manually at the SRM prompt.
TIA,
Jack
