Thanks, that's a slightly safer method than my manual method from 
single user. I used Live-cd to setup the initial rootlfs and I'm sure 
its use for an update would be a much simpler process. The problem I 
want to avoid is just with /etc not being updated and hassle of 
manual check/update or risk leaving it unchanged then finding out at 
most inconvenient moment that some program no longer works.

I think I'll try to use the script from sysins that Greg mentioned 
but for that need to work out how to make a cd with my own bootfs and 
kernels. That's a good objective as I've too many different systems 
that fail to boot or have other problems after install if I forget to 
replace GENERIC.
