I have thought quite a while about this. At first I would definitely
have agreed to that resounding "yes". Now, I am not so sure any more.
One of the biggest obstacles to accepting the new is of course
clinging to the old. The easier it is to stick to old stuff, the
longer it will take for the new stuff to propagate.
Now, I would actually prefer a clean cut. Yes, all my hard-won
and deep knowledge about Custom Jumpstart and dynamic profiles
will go down the drain. Yes, I will have to rewrite all my clever
i.local class action scripts that create their own r.local cousins
on the fly. That is bad -- for me. But if the new system is better
than the old, so be it.
The key here IMHO is migration tools. There should really be a toolset
that reliably and reproducibly performs the following:
- migrates a set of SVR4 packages into the new format as a set,
preserving as much metadata as possible (i.e. "depend" info etc.)
- converts the easy cases into the new formats automatically
- provides useful hints to the package author (or migration
requester) so that (s)he has a chance to recreate the packate
functionality previously provided by various SVR4 features
- clearly documents the migration, ideally in a machine-readable
fashion (you can tell I've worked for banks :-)
If we have such a toolset, we can dare to make a clean cut. And
that clean cut will make the new world system ever so much better
manageable.
Just my $0.03 (= 0.02 EUR :-)
