Bug#872457: pbuilder: support a hook to be executed for unsatisfiabled b-d and/or any error that stops a build

[Sandro Tosi]

Package: pbuilder
Version: 0.223
Severity: wishlist

Hello,
we have a reporting tool that alerts us if a package build process in pbuider is
successful by using hooks type B and C.

But there is no hook that is executed after pbuilder tries to install b-d and
fail because some of them are unsatisfied.

It would be useful to have such a hook, or something more genering: a hook
executed after every error that makes the build stop

thanks for considering,
Sandro
