Is it possible to build a -current 'installboot', 'bootxx_cd9660', and
'boot' and use it to make a bootable NetBSD-1.4.2 CD?  Ie, can a 1.4.2
kernel be booted from the -current stuff?

If the answer is yes, then my next question is how to build that stuff.  I
downloaded a -current copy of syssrc.  I tried

cd /usr/src/sys/arch/pmax/stand
make

but that failed due to missing includes.    I was hoping to keep this
machine at 1.4.x and not -current and don't have disk space to do a
complete -current build.

Thanks for any help
