/dev/random in jails

[Tech Valley Internet - Tony Kivits]

Hello,

I am attempting to run portions (if not all) of the software called 
HSphere inside of jailed subsystems of FreeBSD.  I am able to create 
the jails no problem but the devices /dev/random and /dev/urandom are 
not created automatically in the jail despite the fact that a handful 
of other devices are mounted correctly when the jail is created.

Is there a specific reason for these devices not being created in a 
jail or is there a way to create these devices so that they will be 
available inside a jail?

Any help on this would be much appreciated.

Thank you,

Tony
