Package: haveged Version: 1.9.14-1 HAVEGED is no longer considered necessary on any linux kernel 5.6 and greater. The site itself recommends[1] not using it as kernel random support is sufficiently improved, making haveged obsolete. Upstream uses a systemd service file with starting conditions[2] for exactly this reason.
Incidentally, issue 998382 notes issues with running haveged both as service and as userspace application. For recent kernels (e.g. Debian bullseye) this does not need to be an issue per se. I want to point this out to ensure it is on the radar. I can imagine such a change might be too invasive on stable.
