That would do it, but that is close to a kludge. In order for it to
stop being a kludge, the variable would have to be standardized and
recognized as a diskless wrapper variable by distribution makers, which
is easiest if it is published in some way by the boot kernel itself.
Still, from little acorns great oaks grow. I'll give it a try. Once I
get the wrapping all clean and pretty for a few distributions, I suppose
that I can agitate for a cleaner solution, perhaps a /proc entry made by
the boot kernel at startup.
Thanks!
