[Nix-dev] Hydra shouldn't notify me in case a dependency failed to build

[Peter Simons]

Hi,

I've received about 12 e-mail messages from Hydra recently because
packages that Git depends on failed to build. Now, I would like to
notified when *Git* fails to build, but I don't want to receive those
e-mails. Is there a way to configure that?

It's somewhat unfortunate, that the message text of the e-mail doesn't
reflect the fact that Git itself actually  bulids fine:

 | From: Hydra Build Daemon <e.dolstra at tudelft.nl>
 | Subject: Hydra job nixpkgs:trunk:gitFull build 382624 FAILED
 | To: Ludovic Courtès <ludo at gnu.org>, Peter Simons <simons at cryp.to>

 | Hi,
 |
 | This is to let you know that Hydra build 382624 of job nixpkgs:trunk:gitFull has changed from SUCCEEDED to FAILED.
 |
 | Complete build information can be found on this page: http://hydra.nixos.org/build/382624
 |
 | The last 50 lines of the build log are shown at the bottom of this email.
 |
 | A summary of the build information follows:

The only way to figure out what happened is by looking at the web site.
The usefulness of those messages could be improved, IMHO, by making the
reason for the failure obvious from the e-mail.

Take care,
Peter
