Question about a alternative impacting on an other
I have a question about alternatives.
There is what I currently have.
I have two important linear algebra librairies which are managed by
update-alternatives as primary:
There are have various implementations. For now, we have a few of them:
* refblas for libblas.
* lapack for lapack.
* atlas which provides both.
Switching to Atlas will update both blas and lapack alternatives.
This will work.
However, if manually, I update liblapack to Atlas:
update-alternatives --config liblapack.so.3gf
Obviously, it won't update the libblas.so.3gf.
In theory, this should not be a problem... However, lapack from Atlas
uses some internal of libblas.so.
IE, if the user has libblas.so configured as refblas.so and liblapack.so
as Atlas. This will break (cf bug #598638).
Is there a way to have a kind of trigger in update-alternatives for this
