years back, there was a 'coldboot', 'reboot' and 'warmboot'.

now, there is just 'coldboot', ie from power up and thru bios. 'reboot',
ie, restart from bios with out power down.

'warmboot' reloaded default kernel to 'memory page zero', or other
'jump to' and reinstalled.

'warmboot' could also be passed a kernel name, which it would load to
'memory page zero', or other 'jump to' and ran as new.

because of what is needed for 'warmboot', i believe it was dropped,
because it was not that much time to reboot bios and new kernel can
be passed as an argument to 'boot prompt'.

somewhere out in cyber, you may find some al programmer has written
a short 'warmboot'. maybe even in c.

if you are meaning 'new kernel' as in rebuild of active kernel,
you may be able to use 'chroot' if you make some changes to files
in /boot and change /boot/grub/grub.conf to recover from bad build.

all in all, easier to just add new kernel to grub.conf and reboot.
