Stretch => Buster: Entropy during boot

[Jesper Dybdal]

The Buster release notes warn about a possibly insufficient entropy 
source during boot and recommends installing "haveged" on systems with 
that problem.

I run a few Stretch systems on old processors that do not support the 
RDRAND instruction.

Can I simply install "haveged" on the Stretch systems *before* the 
upgrade to Buster to avoid problems during the upgrade?

Thanks,
Jesper
