Please, can you check the list archives? I think we solved it for other files, but it might have been respawned in lnxboot.S. > DragonFlyBSD: > > This was easy.

Anyway, you should tell us the initial error. Thanks! -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call… if you are unable to speak?
