I see two ways to go forward here:
- add symbols files for the libraries and keep them uptodate
- require libraries and utilities to have the exact same version
(upstream does not guarantuee ABI/API stability yet AFAIK, only
on-disk-format stability).
I'll evaluate the symbols route tomorrow to see how much work it is
(starting from 0.6.5.11-1).
furthermore, the question of how to handle the userspace -> module
dependency needs to be solved somehow. again, there are two basic
possibilities:
- add a versioned dependency to the same major version now, and bump it
whenever incompatibilities are known
- always depend on an identically versioned module
thoughts?
