uuid generation on linux boxes

[Ian Holsman]

I have a issue with a linux box not having enough entropy and hanging on 
a call to apr_uuid_get (as it calls /dev/random)

I was wondering why we don't just use /proc/sys/kernel/random/uuid
and use that for our uuid?
also.. as a side topic to the linux gurus out there..
is there any way of generating/adding entropy to /dev/random so it can 
unblock?

TIA
Ian
