Usualy not, a variation of it should happen at install time on all systems
not providing a (good enough) random number generator internally. Taylor
is working on covering more systems. Installation will (in the future)
detect this state and offer solutions.

Once the "full entropy" state is reached, it usually persists - on proper
shutdown the seed file is written and restored on next boot.

This is all kind of in flux currently, so there is quite a bit of confusion
and different advices floating around.
