Comment 5 for bug 1891403

haveged was installed all along for autopkgtests. For package builds, I don't think that's the case.

A link to a failing autopkgtest would be useful I think.

Julian added a launchpad-buildd task - the question there is if you want to install rng-tools too, to use the host's /dev/hwrng to feed /dev/random for package builds. I guess that's not strictly for launchpad-buildd but for the cloud images you're using?
