bug#36380: service urandom-seed takes too long on boot

Hi Leo!

Yes, see [1]:

“-object rng-random,id=id,filename=/dev/random
Creates a random number generator backend which obtains entropy from a device 
on the host. The id parameter is a unique ID that will be used to reference 
this entropy backend from the virtio-rng device. The filename parameter 
specifies which file to obtain entropy from and if omitted defaults to 
/dev/urandom.”


Bye
