I have done this using

This particular sequence will identically clone the package
state of the system -- you probably don't want that, since that
would remove your hard-won new kernel, so you might want to skip
the clear-selections step, and/or you may want to edit the
file.
I think in either case, installing already-installed packages
is harmless.
