Thanks to all, and particularly Peter for this complete explanation.
I had taken makeworld.html from the handbook and used links to save as formatted
text prior to printing out the contents.
Not being familiar with single user mode, I didn't realise that only / was
mounted in that mode (so why does the handbook put "fsck -p" as the FIRST
command, before "mount -a" ? <sigh>).
Not being familiar with sh (and not thinking too well either) I assumed that
"make buildkernel # make installkernel" was two linked commands on the one line,
wheras it should have been read as:
# make buildkernel
# make installkernel
with the # simply indicating root prompt (Thanks, Sue).
All-in-all there was actually nothing wrong (except my ignorance <g>)
