variables with random values

[Giorgio]

Hi,

I'm writing a shell script within barebox to assist an embedded board
initialization process. Some commands in the script do firmware
download with tftp; to allow initializing more than one board at
a time I need to assign every board a random ip address; I would
like to have a shell variable that every time it is dereferenced
it results in a new random (8 bits) value so I could write:

eth0.ipaddr=10.$RND.$RND.$RND

Is there a way to do something similar in barebox ?
