I think it is because openssl fails to write data to stdout because collie vdi
write has exited. If so, we can safely ignore the error message.
I've tried the following simpler version. It looks working correctly without dd

_random()
{
openssl enc -aes-256-ctr -pass pass:"$(date)" -nosalt < /dev/zero

}
