|
This option enables UML's "hardware" random number generator. It
|
|
attaches itself to the host's /dev/random, supplying as much entropy
|
|
as the host has, rather than the small amount the UML gets from its
|
|
own drivers. It registers itself as a rng-core driver thus providing
|
|
a device which is usually called /dev/hwrng. This hardware random
|
|
number generator does feed into the kernel's random number generator
|
|
entropy pool.

If unsure, say Y.
