Any hope in making systemd-random-seed(8) credit that "random seed
from previous boot" file, through RNDADDENTROPY, *by default*?

Because of course this makes the problem reliably go away on my system
too (as discussed in the original bug report, but you were not CCed).

I know that by v243, just released 12 days ago, this can be optionally
done through SYSTEMD_RANDOM_SEED_CREDIT=1. I wonder though if it can
ever be done by default, just like what the BSDs does... This would
solve a big part of the current problem.
