Brian, thanks so much for your advice. Thank you also Felix, David, and
Bastien --- i need to study what you have all written.
However, Brian's final stanza is so simple that i can ask a question about
it immediately.
And that is: how can grub2 or any other software know what partition
'/boot' refers to?
So i presume that in this very very short stanza you provide, there will
also have to be a search line like David has (search --no-floppy ......) to
identify just where '/boot' is (???).
Thanks everybody for your help!!!
