Use lexicographic order with number prefixes so things "look" the way
the always have but it will be more flexible going forward. I don't know
that IPA will ever actually run out of enough number prefixes for this
to be a serious problem but plan for the worst I guess.
I'd just update the current README that recommends certain levels with
information on the new sorting. The order within a given numeric
subgroup is only important in a minority of cases.

But you haven't explained any case why LDAPI would fail. If LDAPI fails
then you've got more serious problems that I'm not sure binding as DM is
going to solve.
The only case where DM would be handy IMHO is either some worst case
scenario upgrade where 389-ds is up but not binding to LDAPI or if you
want to allow running LDAP updates as non-root.

People do all sorts of strange things. Installing the packages with
--no-script isn't in the range of impossible. A prompt, and I'm not
saying it's a great idea, is 2 lines of code.
I guess it just makes me nervous.

Ok, pretty much the things I was thinking as well. A scary warning
definitely seems warranted.

Ok, I'd add that detail to the design.
