Shouldn't be any troubles doing things this way.  I tend to extract
etc.tgz somewhere and use "diff -rq /etc /new-etc" to get an overview
of what's changed and then copy or update any changed files I need to.

Be sure to reboot with a new kernel too.  Perhaps even do that first
before extracting the userland sets just to make sure.  And save the
old kernel :-)
