The upgrade from the older version of sup to this new one can be complex, as
some configuration files may require manual migration. I have added some
information in the NEWS.Debian file for users. I had envisioned using
maintainer scripts to automate this migration, but this became
extraordinarily complex. Instead, I have updated the Sup Wiki upstream and
linked to that page from NEWS.Debian. If anyone has any suggestions, please
let me know (or just add it).
Yes, this is a hard nut...
I think that we should at least ship the wiki text on how to migrate in
/usr/share/docs, and also mention this in NEWS.
I also raised this question on the supmua mailing list and got an answer
that we might try, verify, and document
