man urandom:
The random number generator gathers environmental noise from device
drivers and other sources into an entropy pool. The generator also
keeps an estimate of the number of bits of noise in the entropy pool.
From this entropy pool random numbers are created.
...
When a Linux system starts up without much operator interaction, the
entropy pool may be in a fairly predictable state. This reduces the
actual amount of noise in the entropy pool below the estimate. In
order to counteract this effect, it helps to carry entropy pool infor-
mation across shut-downs and start-ups.
I guess you can remove urandom from boot runlevel
# rc-update del urandom
or, you can try to troubleshoot the problem (=
The shutdown section of /etc/init.d/urandom is pretty much one line on
my system:
dd if=/dev/urandom of=/var/run/random-seed count=1 &> /dev/null
You can try seeing what's wrong with that...
