I've tested 4.19 with the changes from 50ee7529ec45, and it appears to
do the expected thing. The kernel claims to have enough entropy at boot
that ssh host key generation happens quickly.
This change is likely to also address #931644. I've asked the submitter
of that bug if they'd be able to test a proposed fix.
I will prepare a merge request and note it here when it's available.
