I don't think you have to boot into the new kernel in order to perform
the following builds - after all build.sh works cross platform, surely
it will work with the previous version. On the other hand, that might
be considered a good test for the new kernel, so there you are.

Almost always I build.sh release - takes longer, but is a better test
in my view; I also create the ISOs and use them on a few more machines
(using the update option of the installation procedure).

That's done if you use the created CDs, you just have to be careful to
take a notice of the results.

I unpack the newly created etc.tgz and xetc.tgz into an empty
directory, say, /tmp/x, and

/usr/sbin/etcupdate -a -w 150 -p less -s /tmp/x

(in a large xterm - easier to do the interactive merge).
