1. Thanks, Freddy, for starting this nice thread. We're seeing a nice interesting
interaction among forum members here as a result.
2. I've used the two update features on occasion in the past as a means of preserving
my persistence file material which I am in the habit of catasrophically over-writing
on occasion. However, it is so easy to package, compact and save a snapshot of
persistence with a mkisofs utility, I currently prefer that approach.

1. Greetings, nice to hear from you. I hope you'll post more details of just how you
manage your Knoppix re-masterings.
2. My op ed earlier was slanted toward asking a minimum of Klaus K, trying to stay
within what I think his own framework for producing Knoppix might be.
Other Linux distros have their own minimal configuration from which to build up one's
own tailor-made system. KK could easily dump a 'baseline' iso with very little
additional effort.
3. I think you and I may represent two extremes in using Knoppix. I prefer a mininal
configuration, and like to build up my small Knoppix from overlays. You seem to represent
the 'power user' and can and do tackle larger modifications of Knoppix to get what you
want. One size to begin or end with clearly wont suit both of us.
4. I concur that Klaus K would much prefer a good working example of code for any
suggested improvement of Knoppix. Gilles' contributions to init show how effective this
approach can be.
