Good Q, lemme look at makeit..  Apparently not.  My script keeps a 2nd copy 
of everything so all I have to do to revert if the previous version worked 
is rm the $VER and mv the $VER.old back to $VER.

===================EOF================
I can replace the bZimage copy with a make install, but that would appear 
to need an order re-arrangement.  What can be excised, or moved up and 
where should the make install line go?

I don't want to lose the .old copies, they have been handy in the past.  
Although it does complicate the update-grub since they should up in the 
grub menu too.  Since we have much larger /boot partitions than were  
allowed when I first carved the great great grandparent of this script a 
decade ago, maybe it is time the .old gingerbread did leave.  There is now 
lots of room in /boot for attempts that fail.

That means I probably could:
1. ccache make CONFIG_DEBUG_SECTION_MISMATCH=y -j3 bzImage && \
2. ccache make CONFIG_DEBUG_SECTION_MISMATCH=y -j3 modules && \
3. make install (new)
4. make modules_install && \ (or is this even needed now?)
5. mkinitramfs -o/boot/initrd-$VER.img $VER && \
6 and do the .config saving
7 update-grub
If that is the now correct order, I can do that easy enough.

Sometimes you have to head this old electron cowboy off at the pass.

Thanks Randy.

Cheers, Gene
