I talked with Bruce on this. We see no reason do_install[prefuncs] is required
any longer.
It was when that line was written, but when the kernel was refactored to permit
multiple kernel builds and such the need for this went away.

In do_deploy, I see multiple usages of the KERNEL_ARTIFACT_NAME (sometimes with
alternative variables.. but in the end both PKGV and PKGR are used here.)
do_deploy is after do_package/do_packagedata (where the values are assigned and
stored). So it should be safe for us to use the read_subpackage_metadata (or
something new if desired) to read back in the stored PKGV (AUTOINC) and PKGR
(PRAUTO) values.
