Hi,

/et/init.d/urandom has a $PATH which doesnt include /usr/bin
but the find command (called without the full path) is in /usr/bin
So, the pool size value is not processed:

/etc/init.d/urandom: 1: find: not found

/etc/init.d/urandom: 76: find: not found
[: 76: Illegal number: 

Adding /usr/bin to $PATH fixes the problem (or maybe calling find with its
full path)

Regards

Jean-Luc
