 The OpenBSD policy on openness extends to hardware documentation : in the slides for a December 2006 presentation , de Raadt explained that without it " developers often make mistakes writing drivers " , and pointed out that " the [ oh my god , I got it to work ] rush is harder to achieve , and some developers just give up . " He went on to say that vendor @-@ supplied binary drivers are unacceptable for inclusion in OpenBSD , that they have " no trust of vendor binaries running in our kernel " and that there is " no way to fix [ them ] ... when they break . "
