There's always a tradeoff in hiding what is being done between
simplifying things and making it completely impossible for anyone else
to understand it or fix it if it breaks when you aren't there.  I like
a little balance between the extremes.  Like making the scripts that
do the work visible, but including some sanity checking so it won't
run on the wrong machine - or anything else that you can guess ahead
of time someone might do wrong with it.   But you could embed the same
thing in a cgi kickstart URL if there is some way it can deduce the
right file to deliver or make your db restore process add/configure
any missing packages needed at that point.
