According to the man page it's alre
Hi Daniel,
interesting failure mode ;(

Hi Etienne,
Hi Arjen,
Hi John,
Hi Jo,
while wondering which process is blocking my rootfs from being
unmounted for sysupgrade I discovered that getrandom story going

2) save a seed at /etc/urandom.seed if it doesn't exists
3) save a new seed each boot at "system.@system[0].urandom_seed"
(see /etc/init.d/urandom_seed)
